Help with breakable wall!!

[FlawlessHappiness]

I don't think this line will work:
AddEntityCollideCallback("", "AREANAME", "WallCrush", true, 1);

Since you have no asParent, there will be no collision, and therefore the callback will not call.
Instead, you can define all the objects you're gonna need.
Call all the objects: "BreakWall_1, BreakWall_2, BreakWall_3 etc.
After that, create a for-script, and make it work with the collide function, so you can write:
AddEntityCollideCallback("BreakWall_"+i, "AREANAME", "WallCrush", true, 1);
