assigning a vlaue to a variable in only one part of an if-else statement C#

I'm a fairly new c# coder and I wrote a code that uses filehelpers to parse a csv and upload the data to a SQL server database. The issue I'm having is with a variable in my if-else statement.

Code below:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using FileHelpers;
using System.Data.SqlClient;
using System.IO;

namespace OnQ_prototype
{
    class Report
    {
        [DelimitedRecord("\t")]
        [IgnoreEmptyLines()]



        public class ColumnReportNames
        {
            public String textbox22;
            public String textbox29;
            public String textbox24;
            public String textbox23;
            public String PSFullAcct;
            public String AccountDescription;
            public String BusDateAmount;
            public String ThisPTDAmount;
            public String LastPTDAmount;
            public String ThisYTDAmount;
            public String LastYTDAmount;
            public String BusDatePctAvail;
            public String ThisPTDPctAvail;
            public String LastPTDPctAvail;
            public String ThisYTDPctAvail;
            public String LastYTDPctAvail;


        }

        static void ProcessFilesCSVFiles(string originalPath, string destinationPath)
        {

            foreach (var GenesisDirectory in Directory.GetDirectories(originalPath))
            {
                foreach (var inputFile in Directory.GetFiles(GenesisDirectory, "*.csv"))
                {

                    string lines = inputFile;

                    FileHelperEngine engine = new FileHelperEngine(typeof(ColumnReportNames));
                    var records = engine.ReadFile(lines) as ColumnReportNames[];
                    foreach (var record in records)
                    {
                        Console.WriteLine(record.textbox24);
                        Console.WriteLine(record.textbox23);
                        Console.WriteLine(record.AccountDescription);
                        Console.WriteLine(record.BusDateAmount);
                        Console.WriteLine(record.BusDatePctAvail);



                        string Description = record.AccountDescription;
                        string column;
                        string amount;
                        string amount2;


                        if (Description == "Total Occupied                ")
                        {

                            column = "Total_Occupied";
                            amount = record.BusDateAmount;
                            amount2 = record.BusDatePctAvail;



                        }
                        else if (Description == "Total Rooms Occupied")
                        {
                            column = "Total_Rooms_Occupied";
                            amount = record.BusDateAmount;

                        }
                        else if (Description == "Total Available Rooms")
                        {
                            column = "Total_Available_Rooms";
                            amount = record.BusDateAmount;
                        }
                        else if (Description == "Rooms Average Daily Rate")
                        {
                            column = "Rooms_Average_Daily_Rate";
                            amount = record.BusDateAmount;
                        }
                        else if (Description == "Total Net Rooms Revenue")
                        {
                            column = "Total_Net_Rooms_Revenue";
                            amount = record.BusDateAmount;
                        }
                        else if (Description == "Revenue Per Available Room")
                        {
                            column = "Revenue_Per_Available_Room";
                            amount = record.BusDateAmount;
                        }
                        else
                        {
                            continue;
                        }


                        SqlCommand cmd;
                        SqlConnection conn;
                        conn = new SqlConnection("Data Source=hureports01;Initial Catalog=hureports;Integrated Security=True");
                        conn.Open();
                        var sqlCommand = string.Format(@"MERGE [OnQReport] AS target USING (select @Property as Property, @Date_of_Report as Date_of_Report, @Percent_Occupancy_PAR as Percent_Occupancy_PAR, @val as {0}) AS source ON (target.Date_of_Report = source.Date_of_Report) WHEN MATCHED THEN UPDATE SET {0}= source.{0} WHEN NOT MATCHED THEN INSERT (Property, Date_of_Report, Percent_Occupancy_PAR, {0}) VALUES (source.Property, source.Date_of_Report, Percent_Occupancy_PAR, source.{0});", column);
                        cmd = new SqlCommand(sqlCommand, conn);
                        cmd.Parameters.AddWithValue("@Property", record.textbox24);
                        cmd.Parameters.AddWithValue("@Date_of_Report", record.textbox23);
                        cmd.Parameters.AddWithValue("@Percent_Occupancy_PAR", amount2);
                        cmd.Parameters.AddWithValue("@val", amount);
                        cmd.ExecuteNonQuery();
                        conn.Close();

                    }

                    var newFileName = DateTime.Now.ToString("MMddyyyy") + ".csv";
                    destinationPath = Path.Combine(GenesisDirectory, "Completed");
                    Directory.CreateDirectory(destinationPath);
                    var destinationFileName = Path.GetFileName(newFileName);
                    destinationPath = Path.Combine(destinationPath, destinationFileName);
                    File.Move(inputFile, destinationPath);
                }
            }
        }


        static void Main(string[] args)
        {
            try
            {
                ProcessFilesCSVFiles(@"C:\Users\btajfel\Documents\OnQ", @"C:\Users\btajfel\Documents\OnQ");


            }

            catch (System.Exception e)
            {

                Console.WriteLine("An error occurred: '{0}'", e);
                Console.ReadLine();


            }

        }

    }
}

If you look at my first if-statement, you can see that when that is the column name I set amount and amount2, to different values. In the rest of my else-if statements i give amount a value but not amount2. The reason for that is because I only want the value of record.BusDatePctAvail when the column is "Total Occupied ". Other than that, I don't need the values for record.BusDatePctAvail. The issue that I'm having is that in my statement cmd.Parameters.AddWithValue("@Percent_Occupancy_PAR", amount2); it says "use of unassigned local variable "amount2"". I believe the reason for this is because it is not assigned throughout the rest of the else-if statements but I may be wrong. If that is the issue, how would I fix this?
