Rep Power: 0

Hi, newbie here, don't want to spend money on this simple task, but not as easy as the youtube video let me to believe so far. I think I don't need to unscrew the 3 screws, and I need to turn counter clockwise when I am facing the back of the lightbulb(or looking at the 3 screws), but I won't be able to turn the lightbulb one bit. what am I doing wrong? anyone has any suggestions for me? thanks!!
