Repeating fields are best used for display only and not for data manipulation. You would be better served by using a related table with individual records to store your data.
my 2 cents . . .
Thanks Rick and David,
I particularly liked the Repeating Fields=Death...very humorous and to the point.
Fortunately I don't have this problem, but what if I wanted to do that (use a portal to replace repeating fields) within a portal? I'm correct in assuming that you can't make a portal in a portal, right?
Thanks for the advice...I'll go the proper route and avoid the "death defying" shortcut :)
