[Zope] Document Template Parse Error

[worona]

Using Zope 2.4.3, I am receiving a "Document Template Parse Error" when 
trying to use a dtml-let tag in a DTML Document.  The content for the 
site was copied from a Zope 2.5 server using ZSyncer.  When I add a new 
document and try to use a simple dtml-let tag such as the following:

<dtml-let myval="my value">
 <dtml-var myval>
</dtml-let>

I get the error listed below.  Hopefully I am missing something simple.  
Any
