Can't edit fields in a tab control via Instant Web Publishing
I have a database that I'm sharing via Instant Web Publishing. It has two layouts, each with a tab control, and each tab control has 5 tabs. On layout A, I can edit all fields on all tabs. On layout B, I can't edit any of the fields on the 5th tab (but I can edit fields on the other four tabs on this layout). I've checked and re-checked to ensure that the accounts I'm using have access priviledges to those fields, that those fields can be entered in browse mode, and that they're not locked. Why can't I edit those fields on that one tab, on that one layout? Is there some other formatting thingy that I should check?
Thanks for any and all suggestions,
