David-

I heartily suggest that you try simplying the situation. Get a form working reliably, piece-by-piece. At this point, there are so many variables involved that it's a bit of a trick (for me) to make a suggestion other then what I've thought of so far. Probably just a lack of imagination on my part. ;-)

>Alas, succintness is not one of my virtues (had you noticed??).
I feel I can laugh, since I'm not known for brevity, either. :-D
