When posting code, please use Copy/Paste so we can see
exactly what you are using when a problem occurs. Your code
above has so many typos that I can't tell if the code is bad
or if you just typed it here improperly.

Your problem description is also dificult to decipher, but
the way I interpret it, I can not see how that code logic
can cause the problem I think you are describing. I'm
guessing that you have some other code that is causing
whatever is going wrong.
