Pete,

I did it and it is working great, I really appreciate your help.
Only one issue pending, I have now 3 Listing Types (NEW, USED and RENT) and I created 3 new Categories (Form Used, Form New and Form Rent) and build the forms on them and assigned them as General Category for each Listing Type.
Ok, everything is fine but the new categories are shown in the select boxes, and I made them Locked so they appear as in the picture attached, can i make them invisible??
