Hi Jason, yes just testing as you answered, that doesn't seem to cause a conflict. However something isn't right, just looking at it now.
Tab1 should insert contact & case, it actually inserts 2 identical contacts & 1 case
Tab2 should insert case linked to existing contact, it actually inserts 1 blank contact & 1 case but not linked to correct contact!
I have attached page its gone really wrong somewhere!
