I'm not sure what I am doing wrong.

I keep getting this error Program.cs(16,25): error CS0019: Operator -' cannot be applied to operands of typestring' and `string'
Compilation failed: 1 error(s), 0 warnings

I program in java, so I don't know how different C# is, but you can't subtract strings from each other. It looks like you'd want to replace your minus sign with a plus sign in this line:

Console.WriteLine("You've entered " - entry + " minuets");

so that it looks like this: (also it looks like you have a spelling error in "minutes"

Console.WriteLine("You've entered " + entry + " minutes");

Thanks! Oh yeah I spelled minutes wrong too... but hmmm that still doesn't solve it...

I'm still getting Program.cs(16,25): error CS0019: Operator -' cannot be applied to operands of typestring' and `string'

Hello Elizabeth Pasek-Allen,

The answer Brendon Butler provided should fix the issue. I modified and compiled the code to confirm. If you're still getting this error, try using the following code.

using System;

namespace Treehouse
{
    class Program
    {
        static void Main()
        {
            //Prompt the user for minuets excerised
            Console.Write("Enter how many times you excercised: ");  

            string entry = Console.ReadLine();

            //Add minuets excercied to total
            //Display total minuets excercised to the screnn  

            Console.WriteLine("You've entered " + entry + " minuets");
        }
    }
}

I hope this helps.
