Wow, that's made my day, works perfectly! I didn't realise you could use Tmp-* as a request "type" variable - does it belong in request or control, I've always assumed the latter but it makes things more concise due to the assumed request type. Anyway, really appreciate the time you took to try stuff out there Alan, thanks again.

Had an earlier attempt was to break it down, guess I might have come at it from the wrong angle, i.e. trying "%{xlat:%{control:Tmp-Integer-0}}". I imagined that piece to be expanded first into and integer, in the way bracketed things work inside -> out.

"%{Control:Tmp-Integer-0}" is fine, gives the correct number, no great surprise there.

I can't test "%{control:Tmp-String-3[%{control:Tmp-Integer-0}]}" as the server won't start up since it doesn't see control:Tmp-Integer-0 as an actual integer.

Yes. I did this: update request { Tmp-Integer-0 := 1 Tmp-String-0 += "a" Tmp-String-0 += "b" Tmp-String-0 += "c" } update reply { Filter-Id := "%{xlat:Tmp-String-0[%{Tmp-Integer-0}]}" } and it worked. The Filter-Id had 'b' as a value. Alan DeKok. - List info/subscribe/unsubscribe? See http://www.freeradius.org/list/users.html
