loading up ammo boxes

I havnt played Flashpoint in a few years but decided to load it back up
recently. I used to be able to create ammo boxes in strategic locations
and load them up with the initialization scripts, but I cant remember
how to do it. Ive found a few messages that demonstrate it, but i cant
get them to work for me either. Can somebody walk me through adding a
box and adding ammo to it so that it actually works?

thanks

yea, create the ammobox, give it a name (id) for exmaple "myammobox"
then create a script file like this which u have to call once at the
mission beginning:

clearweaponcargo myammobox;
clearmagazinecargo myammobox;
#loop
myammobox AddMagazineCargo ["mavericklauncher", 64];
myammobox AddWeaponCargo ["mavericklauncher",64];
~30
goto "loop"
