Hmm, here is what I have, in DTML Method aaabbbccc::

 <dtml-var standard_html_header>

 <p> Calling asdf with variable 'foo' = 'bar', using the let tag: </p>

 <dtml-let foo="'bar'">
   <dtml-var asdf>
 </dtml-let>

 <dtml-var standard_html_footer>

And in DTML Method asdf::

  <p> <dtml-var foo></p>

When I view aaabbbccc, I see::

 Calling asdf with variable 'foo' = 'bar', using the let tag: 

 bar

which is exactly what I expected.

Can you see any differences between your code and mine?
