Hi; I'm trying to concatenate a <dtml-var> with a string. I have this poor

attempt:

...

<dtml-var expr="_.string(title_or_id.'_frame')(_,_.None)"> where *title_or_id* is (of course) the <dtml-var> and *_frame* is the string. How should I do this?

you could try

<dtml-var title_or_id>_frame

This won't do because I forgot to mention I need to concatenate this and call it as a <dtml-var> (apologies to Andreas Jung).

<dtml-var "_.string(title_or_id)+'_frame'">

This threw the following error: Error Type: TypeError Error Value: object is not callable: File /apache/ZopeInstallation/Zope_software_home/lib/python/DocumentTemplate/DT_Util.py, line 231, in eval (Object: _.string(title_or_id)+'_frame') (Info: title_or_id) File <string>, line 2, in f (Object: guarded_getattr) TypeError: (see above) Suggestions?
