JOptionPane and If Statements

I am writing a program for my class and the program compiles and runs. There doesn't seem to be anything wrong with the logic in my "IF Statements" however, each time I get the same results no matter what values I enter for Growth Rate and Inflation. Does anyone see where I am going wrong.

Code:

import java.util.Scanner;
import javax.swing.JOptionPane;

public class Economy
{

public static void main(String[] args)
{
  Scanner stdIn = new Scanner(System.in);
  double GrowthRate=0;           // Economic Growth Rate
  double Inflation=0;            // Inflation Rate


JOptionPane.showInputDialog ("Enter the Growth Rate % (as a whole number): ");

   // System.out.print("Enter the Growth Rate % (as a whole number): ");
    //GrowthRate = stdIn.nextDouble();

JOptionPane.showInputDialog ("Enter the Inflation Rate % (as a whole number): ");

    //System.out.print("Enter the Inflation Rate % (as a whole number): ");
    //Inflation = stdIn.nextDouble();
    //System.out.print ("Based on the above information, you should: \n\n");

    //First If
    if (GrowthRate < 1 && Inflation < 3){
        JOptionPane.showMessageDialog(null, "Increase welfare spending, reduce personal taxes, and decrease discount rate.");
    }
    else
    {
        JOptionPane.showMessageDialog(null, "Reduce business taxes.");
}
    //Second If
    if (GrowthRate > 4 && Inflation < 1){
        JOptionPane.showMessageDialog(null, "Increase personal and business taxes, and decrease discount rate.");
}

        //Third If
        if (Inflation > 3 ){
            JOptionPane.showMessageDialog(null, "Increase discount rate.");
}




}
} // end main
