says:
2. AutoGen FOR macros must be in one of three forms:
FOR <name> [ <separator-string> ]
FOR <name> (...Scheme expression list)
FOR <name> IN <string-entry> [ ... ]
where:
‘<name>’ must be a simple name.
In other words, you cannot use categories.category.
Instead, just use nested invocations of the first form:
[+ FOR categories +][+ FOR category +] ... [+ENDFOR+][+ENDFOR+]
Also, the conditional ``[+ IF (len "categories") >= 1 +]'' is
both unnecessary and incorrect. The FOR won't iterate over
categories if there aren't any. The correct spelling is:
[+ IF (>= (len "categories") 1) +]
It has to be a valid Guile/scheme expression.
> [+ categories.category.title +]
If you are wanting the title for the current category, lose the
name qualifications. The search for this three part name will fail
at the current ("category") level, try and fail at the "categories"
level and succeed at the top level.

You're welcome. Good luck! Cheers - Bruce
P.S. using another variant of the template:
$ cat joomla-2.5.6.tpl ; autogen joomla.def;cat joomla.sql
[+ AutoGen5 template sql +]
[+ (get "template") +]
[+ (get "defaults.language") +]
[+ FOR categories \+]
[+ FOR category \+]
[+ title +]
[+ ENDFOR \+]
[+ ENDFOR categories +]
