my box problem

[mcgoo]

i have created a map with boxes that are breakable. i have stacked acouple of these boxes on top of one another. if i destory the bottom box, the top box stays in midair. is there anyway to make it so the top box falls after i destory the bottom one?
and also, is there a way to change how much damage the boxes will take before they blow up? thanks

box gravity, no
box damage, yes.

If it is a SP level, you can trigger a script when the bottom box is destroyed to move the top box down.

In a complex stack of boxes, this could be tricky to make it work 'naturally'.
