what thomas said, but next time you ask a question only send the important code snipped( in this case that is the code in between the asterisks)

1. You wrote `alert` and `form` within `main` method block. Now, I don't know C# much, but I think you better move `alert` and `form` out of `main` method block, just to be clear structurally. 2. Inside `alert` method, move the while loop up before the `if` block that checks whether <choice> equals to "yes" or "no". This way, when you exited the while loop you are left with only 2 possibilities (a "yes" or a "no"). Use `continue` to repeat the loop while <choice> neither equal to "yes" or "no". 3. IIRC in C#, string comparison is done by the help of `Equals` method. I suggest you to employ that method for checking string equality, rather than relying on the != or == operator. Talk to me if you have doubts ...
