I hate to beg but I really need an answer. I've been over this and over
this - I've tried everything I could think of and cannot get it to work.
Part of my problem is that I'm still developing an understanding of
"Fields". The two books I have on Palm programming don't go into fields
much. I've also reviewed the SDK's but it hasn't all clicked yet. (I've
also searched the Palm Dev Knowledgebase and the archives of this
newsgroup.) I'm sure that what I'm trying to do is possible - it probably
just needs some re-arranging of my code. So...if anyone could help it would
be greatly appreciated.
