You were initially trying to assign the value of null (which may have not actually existed) to SerialNumber. -- Patrick Lewis <[EMAIL PROTECTED]> ___ Zope maillist - [EMAIL PROTECTED] 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 )

Correct me if I'm wrong. If the SerialNumber is taken from a ZSQL method, shouldn't you been able to show it without testing its content. Such as: Those rows that have something other than 'null' would be shown together with a .

[Zope] simple dtml-if question
How do I do this? I have a table with a field called SerialNumber. I want to test it for null and return a non-breaking space if it's null. Here's what I tried: Doesn't work (be nice-I'm new). I've tried various combinations of quotes - no quotes but apparently haven't hit it just right yet. What I'm trying to do is stick SOMETHING in an empty cell so netscape doesn't remove my borders when it encounters the empty cell - is there an easy fix?
