        {            
            string input = Console.ReadLine();
            string output = Console.WriteLine();
            if (input == "quit")
            {
                string output = 
            }
            else
            {

I think you meant "string", not "thing",

So to "Declare the output variable ,,,, and assign it to an empty string (i.e. "")." would look something like this:

                string output = "";

That's the correct answer to the question you asked, but it's not the only thing you need to do to complete the challenge.

Check the instructions again, and be sure to do everything in the "To fix this error" section, but also don't do anything else (like removing the strings being assigned, you'll need those back).

If you start over and follow the instructions carefully, then if you still have trouble you might try creating a new question so it will show the code with the suggestions applied.
