Dude, it's this simple:
- if the js validation doesn't occur/is faulty, look at the outputted html
source/js. If you don't find the problem, post in comp.lang.javascript.
- if the PHP validation doesn't occur/is fault, only then look at the PHP
code, and post here.

Ergo: Now your js doesn't work. Take the outputted pagesource, ask the
people at comp.lang.javascript. If you had done that in the first place, you
might already have had the correct answer.
