I tried

<dtml-let item="sonstiges.help.sonstiges.err.getitem(_.str(httpcode))"> <dtml-if item> <dtml-var "item.title()"> <dtml-else> NO ITEM </dtml-if> <dtml-let> ... What is wrong with my code? Any ideas how to solve the problem? I see at least one problem (there may be more):

I do not expect that your "err" object implements a "getitem" method. You should get an "AttributeError getitem". When you are sure, that no object with an "HTTP" error code as name can be acquired, you can use: "_.getattr(...err,`httpcode`,_.None)" When you are not sure, you can try "_.getattr(...err.aq_explicit,`httpcode`,_.None)" This usually works, but it not truely safe. For a safe solution search the archives for "aq_base". Dieter
