Umm. The floor should be trigger #30, the place with blue players in it should have area ID 0 in bottom right and top left corners, and place with red players should have area ID 1 in bottom left and top right corners. There should also be an animation next to the springs with the first frame as a half- or unmasked block, and the second frame as a fully masked block. The trigger ID here should be #29.
E: Remember the gamemode too.
