Hi,
I'm new with javascript just for the mentioning. Anyway, I made a custom code, but can't figure out why the form continues to submit even when the argument is FALSE. I've just about had it with this onSubmit stuff. P.S. if you could copy the code and reply it with corrections, it would be helpful.
Thanks, here is the new custom script:
