Hilary,
I have another question. I've found a workaround for the date issue: I'm locking down the list to read only, so the date will never be modified from the list - problem solved.
However, when I have multiple rows in my repeating table, and I delete one of the rows from the repeating table, it doesn't get deleted from the sharepoint list. On the other hand, if I only have one row in my repeating table, and I delete that row from the repeating table, it DOES get deleted from the sharepoint list. Everything else works fine. I can modify any of the rows and the corresponding list items will get updated. It's just the deletes that don't work unless I have only one item in my repeating table.
Any ideas?
