Hi Try <dtml-let criteria="'1=1'"> The bit inside the double quotes is evaluated as a python expression, and thus returns the string you want. See http://www.zope.org/Documentation/Guides/DTML-HTML/DTML.10.html hth, -- Marcus

I'm trying to assign the string:

1=1

to the variable criteria using this construct:

<dtml-let criteria='1=1'>

but I can't because Zope complains:

invalid parameter: "=1'", for tag <dtml-let criteria='1=1'>, on line 5 of Create_List

Some playing around reveals that it doesn't like spaces and the equals sign (=) in the string.

Am I correct in thinking that something delimited by single quotes (eg. 'this is a string') is a string? If so why can't I (or how can I) include spaces and the equal sign inside the string.

thanks - Jason Wong
