You're not REALLY using the 1.4.1 version, are you? If yes: that version of FSF is quite old and I can't help you on that. If no: why are you posting in a thread that implies that? (see also...

Hi!

It has been asked at another place on the board when FSF will work with 1.5. Well it looks like the 1.4.1-version compiles without modifications on 1.5 (which means: it worked all the time)....

I think this won't work the way you want to. You want the max/min of the faces on a cell. But what you get is the total max/min.

Maybe a quick fix could be the following expression in funkySetFields (havn't got the time to try this out so the syntax might be slightly wrong):
