As of your last attempt, there's no {{++}} in FTL. You can't change variables without an assignment.

> It would be nice to assign to a map this way:
> {code}
> <#assign map["key"] = 1>
> {code}
> and also 
> {code}
> <#assign map["key"]++>
> {code}
> So far I think it's like this but can't get it work:
> {code}
> <#assign map += {classification.classification : map[classification.classification]!++}>
> {code}
> Thanks for considering.
