URGENT- String to keep people from entering numbers in hangman progra

routy

I put a do while statement where it says 2nd player enters letters. It is suppose to stop user 2 from putting in numbers.If they do, message should pop up,"enter letters only".. It also should not prompt the hangman body to go forth due to it being wrong letter nor should it go to the incorrect letter box. All it should do it prompt a message and ask to enter a letter again after that.
I can not get this to work. Please look at my code. This assignment is due tomorrow.I've been working hard on it.I hope I found a VB site that actually answers questions.
Thank you ROUTY
