can anyone point me in right direction...? have used MX Kollection to produce dependent drop-down menu - it works fine with two form elements but i need three - i.e. i need them to select from "commercial" or domestic", which needs to populate a second menu listing relevant brands, then click on brand to get list of models in third box.i can get it any two menus to do A to B or B to C but if i try doing all three, only A to B or B to C works - code follows- anyone got any pointers - much appreciated. thanks
