Hidden field remains visible after desecting

Hi.

So far I am enjoying Jotform a lot, but I can't seem to resolve a problem with a hidden dropdown list.

Depending on the checked checkbox (multiple are possible) a new form fields appear corresponding to that checkbox. So I have created conditions for each checkbox value. Two of the main checkbox categries (One Shots and Sound Presets) actually require a deeper level of conditions. So when a user makes a selection, a second dropdownlist appears after that selection.

This all goes well, until you uncheck the main category checkbox. Then the second dropdownlist does not disappear. I have enclosed a screenshot to the condition I created for the second dropdownlist.

Thanks in advance,

Perry
