i have made a webform, and i have a script for the handeling of this form (php) this script works fine, but i also made a javascript error checker, now when i try to get some php in that script, it somehow bugs, and doesn't check my errors, in javascript,
below you will find the code i wrote for the error handeling, i'm not finished yet, but i'm currently stuck, since i need to go to my database to check something, and the javascript error handler bugs there.
quick walktrough: I myself have 0 karma for the purposes of testing this error handling. i click submit, and even tho i haven't filled in my username, it doesn't show an error. and brings me directly to the php handler wich does find errors.

I can't see what the problem is, or why it won't work because i'm not skilled enough yet in javascript.
Thanks in advance, Jonathan
