Look into <dtml-try> and <dtml-except>. That should do what you need.

I was trying to give a more friendlier message than the Zope error_message when someone accidentially enters a duplicate Primary Key name of an existing record. Error Type: IntegrityError Error Value: (1062, "Duplicate entry 'Big Foot' for key 1") I have tried the following in my <dtml-var standard_error_message> , but it did not worked: <dtml-if "error_type=='IntegrityError'"> <h3>Duplicate Entry!</h3> <LI>This is a duplicate entry of an existing Database record. Please rename your entry. </dtml-if> Thanks, Mike _______________________________________________ Zope maillist - Zope@zope.org http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )
