Do you mean the values that allow an item to be revealed? Because that would be correct. Every item in Option B has all the options of A added to it, Done so that A could be a Lookup and tied in as well. Might just need to rethink my approach here.
Edit: I added back the little reset function as well and now it seems to be working great! Changing the top one resets all the values regardless and if you skip down there aren't any that a secretly set behind the scenes.
Not going to argue with it, it works and that's good enough for me.
Thanks for your help!
(Though you haven't seen the last of me, I'm sure I'll be back in a bit to figure out why on another form CAML query just keeps saying either the column can't be found or the query is incorrect) :)
