Ok ive been trying to add some maps to my main menu and only one works it is the closest new map to the top and all the others have no pics and fail to load 1 or 2 seconds into the countdown. The value of the one that works is 450 i dont know if that would have anything to do with it though. I have resighned everything ive put onto it so is there some typr of pattern i must follow for the value or is there something othere? if so what?

EDIT:nvm i got help
