In reply to Dependent Fields
Yes, the module works only for single select fields. That fact is stated on this page, see the phrase above "Note that this mod affects only select Selector (Select (Drop-Down Box)) controls.". I.e. it can't work for Multiple-Select type fields. The search form works because it is treated as a special case and it can produce unpredictable behavior if there would be a triple dependency, that is why there is an instruction on how to turn that feature off.
