I took off my inner tail lights and I cant get them back on. The inner portion has a plastic lip on it and the lip wont attach to the car. I can screw it back in but if I push from behind it pops out. How do I put the inner tail light back on?? PLEASE PLEASE PLEASE HELP!! I NEED TO GO TO WRK!!

Are you sure you have the left and right inners on the correct sides? I dont see what else could be the issue.
