LAVALORD96'S PROFILE

Alright, so here's my problem, I have had a picture be put on screen, then I used the erase picture command to remove it, sound simple enough? Well, not for me unfortuantly...You see every time I add the erase picture command, this error pops up: Sprite_picture line 54: NoMethodError occured undefined method for 'width' nil:Nilclass. So yeah, if anyone would be kind enough to help me figure out how to fix this, it would be GREATLY appreciated.

EDIT: I FIXED THE PROBLEM! Unfortunately I don't know EXACTLY what happened, but I replaced the "Game_picture" and "Sprite_Picture" scripts with ones from a NEW project I made, my guess is that something accidentally was deleted from the old scripts. My brain is fried after this mess. Thank you for your help guys. You gave me the idea after all.
