Thanks this was a big help. I know in the future I'll need to do more scripting. -----Original Message----- From: zope-admin@zope.org [mailto:zope-admin@zope.org]On Behalf Of DA Loeffler Sent: Wednesday, September 11, 2002 8:33 AM To: McDonnell, Larry Cc: 'Zope@Zope.

y is a local variable in the script. Its scope does not extend to the calling DTML method. The script returns the value of y, and then the DTML does nothing with it - it doesn't tie it to a local variable name, so the variable no longer has a name (technical term: it has zero reference count) and it is cleaned up by the Python garbage collector. Hence, either give it a name in the DTML method's namespace: <dtml-let y="int_to_string(num)"> <dtml-var y> </dtml-let> or, if you just want to use the variable once, use it as soon as you get it: <dtml-var "int_to_string(num)"> Alternatively, amend your script to: request.set('y',y) instead of the return statement, and then y will be accessible within the DTML method, and anywhere else called in the processing of that Zope request.
