Okay. First, You need a Prop_door_rotating. add that in, then in the "Model"... Option...Thingy... search for "Door" when you have found a door model you want, exit the browser, and try the other options. they will set sound, if im not mistaken, and your choice of handles. place the door in Ur frame, and compile. I belive this is the right way to do it, but im no source mapper, can't handle the download on steam. anyway, hope I helped a bit.
EDIT: OH! and props_doors/door01_dynamic.mdl doesn't work as a door, only npc_furnitiure.
