Hi all again! I am designing a web site ready to use both SQL and Ms Access DB. I have a relation between say Picture and Category. When I delete a category, all the related pictures category will set to NULL. I have no problem with SQL, I set SetToNull in SQL but when I setting up relation in MS Access, I can't find any option, It raise an error when I want to delete category, how I can make MS ACC to set that field to NULL while deleting that record? Thanks.

woff!! :sigh: is there any answer?! :doh:
