in reply to Call CGI script from another CGI script

Not really a Perl question, but why not just use Javascript to change the action="" desitination, based on the form field variables?

So, for instance, an onChange for a drop-down would call a JavaScript routine that would determine what to change the action to, then when the user hits submit, the script that the form gets sent to, form fields and all, is the one you need to happen.
