C#, Getting user value and resetting it

Right now my problem is getting choice 2 to save and rewrite what was written in choice 1. Choice 3 should then reset everything. Right now i tried with at if inside an if and still not getting it to work.

while (true)
{
    Console.WriteLine("\tWelcome to my program"); // Makes the user select a choice
    Console.WriteLine("[1] To write");
    Console.WriteLine("[2] To see what you wrote");
    Console.WriteLine("[3] Reset");
    Console.WriteLine("[4] End");

    string choice = Console.ReadLine();
    string  typed = ("");

    if (choice == "1") // If 1 program asks for text
    {
        Console.WriteLine("Thank you for your choice, input text"); 
        typed = Console.ReadLine(); 
    }
    else if (choice == "2") // Is supposed to say "You wrote, and what user wrote"
    {
        Console.WriteLine(typed);
    }                            
    else if (choice == "3") //  Resets the text so if 2 is selected it would say "You wrote,     "
    {
        Console.WriteLine("Reset. Would you like to try again?");
        typed = "";
    }
    else if (choice == "4") // Ends program
    {
        break;
    }
    else
    {
        Console.WriteLine("Input not computing, try again");
    }
