looks like you are missing the closing } to your switch statement

also, if I'm remembering right, the way your switch is setup, your "show" case is always going to show, because of the missing break in the "process". Might be the way you wanted it, but just in case after getting the script to run you wont be wondering why its always showing your "show" form.

anyway, hope the missing } fixes your problem.
