Regards, Steve. Regards, Steve I am aware of this, however my problem is as follows. I have four select lists. The user can select items from list A and add or delete them from list B.
The user can then select items from list C and add or remove them from list D. The problem is when there are items in list D and the user then removes an item from list B. This means that list C changes and I need to make sure that the selected items that got inserted into list D are still in list C.
I've not been able to find a way to do this because I dont know when list C is done being populated. This discussion thread is closed Start new discussion.
