I did basically what he said and there is no way to distinguish
a correct or incorrect code until fully entered. make
the first page say enter code. when you press a button
right it flips you to the next page in the sequence of
correct keys. if it is a wrong button it flips you to
a page of incorrect keys, but both look identical. once
the code if fully entered if it was all right it does
the command if not it says wrong code. Hope i explained
that well. but you can see it in the file.

I will send more emails when i get to the pc with the
file on it tonight.
