Can anyone help me? :)

Your best bet is to use local variables to set objects in places for this puzzle. Then when they enter this script area, it checks the local variable amount. If it does not match a specific amount, have the player go back to the spawn and set the local variable back to it's original amount. This will place all objects back in their original place.

So if i set my moving wall to variable, AddLocalVarInt(""Wall", 1);
and my door, AddLocalVarInt(""Wall", 1);.

Then in my,
void OnLeave();
{
if(GetLocalVarInt("Wall") == 2)
{
//Nothing happens...
}
else
{
ChangeMap("10_Crushwall.map", "start", "", "");
}
}

Is this what you mean?
