[Zope] Continued problem tal:condition

[KevinL]

If all of your macros are in zpt_memall, and lkid is going to be either
not there, or the name of one of the macros inside zpt_memall, then all
you should need is:

<div tal:condition="exists:request/form/lkid" tal:omit-tag="">
  <metal:block use-macro="container/zptmac_memall/macros/?lkid">
  </metal:block>
</div>

>From what you've said, that should cover it, I'd imagine.  If the macro
isn't being displayed when you do that, then I'd be looking closely at
the macros (and the source for the pages).  It should display an error,
though, I'd have thought.
