[Zope] SV: [Zope] simple dtml-if question

[peter be]

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: 
<dtml-var SerialNumber>&nbsp;

Those rows that have something other than 'null' would be shown together with a &nbsp;.

Curious.
