HELP ME!!!

I took the door trim off my DC4, to replace a mirror. I am now trying to fit it back on, but I can't seem to get it to fit properly. When I fit it on, while the window seals look perfectly fitted, and the holes seem to line up as well, the trim is still too far away from the door, for example, while the holes match up, the screw/rivet thingy goes straight through the trim, and doesn't catch onto anything. Please help urgently!!
