A couple of days ago, Michael Ramirez “asked me”:http://blogs.adobe.com/formbuilder/2006/08/invalid_flashing_fields_2.html#comments how to do complex validations on forms. He asked how one could have a validation as follows: Given 3 text fields A, B and C and a check box E, A is mandatory only if B and C are filled or if E is checked. I thought this would make a great little sample of both complex validation scripts and what I like to call the “Two Button Submit” technique.
