now now :)

(tested)

<dtml-let variablename="1">
blah blah blah ... ie the scope of the variable
<dtml-var variablename>
</dtml-let>

don't fall into the trap of doing this
<dtml-let variablename="I am a string">
blah blah blah ... ie the scope of the variable
<dtml-var variablename>
</dtml-let>

'cos Zope won't let you enter it (it thinks that the 'I' is a 
variable name). Remember that anything in " " is evaluated as a 
Python expression...

try this instead
<dtml-let variablename="'I am a string'">
blah blah blah ... ie the scope of the variable
<dtml-var variablename>
</dtml-let>

You can have multiple variables set too...
<dtml-let variablename="'I am a string'" bloot="1">
blah blah blah ... ie the scope of the variable
<dtml-var variablename> :: <dtml-var bloot>
</dtml-let>

See lib/python/DocumentTemplate/DT_Let.py for more details...
