How can I set the height for say an ammo box?

I'm assuming you mean the height above the ground. In that case, put the following in its init line:

this setPosATL [(getPosATL this) select 0, (getPosATL this) select 1, [color=Green][b]X[/b][/color]] 

Replace the X with a number, which represents the height in meters.
