Wow, thank you for the fast reply.
So I have them all as lookups now. And it "sort of" does what I want. If the main drop down selected doesn't allow for the value that has already been selectedthen it will reset the list. However, if the value is allowed, it doesn't. This normally wouldn't be a problem but I run into issues because, let's say the main option just has two choices. A or B. A reveals dropdowns C, D, and E to report on a specific issue. But B only reveals dropdown C for a general issue. If I first select A, then set C, D, and E to some values, then switch from A to B, nothing get's reset because the the value in C is still allowed in B. But the rows are now hidden so when it's submitted they are stored.
Is there anyway to just force it to reset all the boxes below whatever dropdown is being selected, regardless of whether the options already below are legal?
