However, this has to be done *before* the form is *created* (not displayed) due to how QF works and since you wouldn't know if the form is valid yet this isn't a good solution. I suggest the setConstants solution. -- Justin Patrin -- PEAR General Mailing List (http://pear.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
