Hi, I have a form with several checkboxes and after the user hits submit my form action goes to a processing form. In this form I need to verify which "checkboxes" are checked and perform an action. <dtml-if expr="use_as_is=='checkbox'"> <dtml-call "REQUEST.set('titleid', 'System Product Manager')"> <dtml-in lookup_product_query> <dtml-in lookup_product_id_query> <dtml-in lookup_empid_query> <dtml-call "REQUEST.SESSION.set('email', email)"> </dtml-in> </dtml-in> </dtml-in> </dtml-if> If I do not check "use_as_is" checkbox I will see this error: Error Type: NameError Error Value: global name 'use_as_is' is not defined If checked it will go the the next <dtml-if> statement and error out. If the boxes are not checked I see an error is there any way to trap or define an uncheck checkbox so Zope does not error. The input form has the checkboxes set in this manner: <input type="checkbox" name="use_as_is" value="checkbox"> Thanks.
