Hello, all. Apologies in advance for the long lines in the error message. I'm running Solaris 7, Zope 2.3.3, MySQL 3.23.28-gamma, ZMySQLDA 2.0.7, and MySQLdb 0.9.0. I'm trying to get the following ZSQL method name sql_select_single to work: select servicedesc, serviceid as parentid from z_service where <dtml-sqltest servicename op=eq type=string> Yes, servicename is defined as a parameter. When I test it manually, it's great. When I try to test it with the following bit of DTML: <dtml-let servicename="'CIP'"> <p class="bodynorm"> <dtml-var servicename> </p> <dtml-var expr="sql.test_select_single()"> </dtml-let> I get the following wonderful error: Zope Error Zope has encountered an error while publishing this resource.
