HTML_QuickForm Validation

Hi, I have a PHP/PEAR based app running in both development and production. In development the form processes effectively but in the production environment it seems to fail, regularly. Below is partial output from:- Var_Dump::display($_SESSION); ... User details ... _Incident Mgt_container Array(4) + defaults Empty array () | constants Empty array () | values Array(2) | | + incident Empty array () | + resus Empty array () | + valid Array(2) | | + incident Boolean (FALSE) | + resus Null (Null) | This is the case regardless of the data entered on the form. We run RH9 on both machines.
