Who can help me to rewrite my javascript file for multiple browsers ? This script does check some fields in a form, and if an error has been found displays the form again with the error message beneath the form item the error was found. At IE 5.0 it works ok, wit IE 6.0 I'm getting an error message and Opera does displays the form everytime on the same page, while everytime the form 'reloads' it must be on a blank screen. Who can help me ?
