Finally figured it out! The item style includes rvprModifyProtect and

rvprDeleteProtect; I had assumed these would prevent the user from

deleting the text, but not prevent me from deleting it in code, but it

turns out that I have to change the style before I can successfully delete.

Thanks for all your help as always.
