Dear All, First of all the links to sample pages. First working sample: http://www.torli.pl/valid/index-val.php
and (if someone want use this mix): http://www.torli.pl/valid/valid.zip Description (how i want it to work): 1. there are two tabs: tab #1 is enabled, tab #2 id disabled. 2. there are separate forms in two tabs 3. when the user fill the value in Field 1 in tab #1 and push Submit button, tab #2 become enabled and triggered 4. if user leave empty Field 1 or for some reason validation of form1 in Tab #1 will be unsuccessfull then the warning message will show up, form submit fails and tab #2 remain disabled What is wrong: the validation is working, because the message for Field1 validation is displaying, but i can't figure out why the form is submited and tab#2 enabled and triggered, when validation for Form1 in Tab1 is unsuccessfull. Thanks for any help or suggestions. Best regards Sławek
