I'm gettin' this ERROR: ardp/Server2.lua:98: attempt to call global 'getWeaponAmmoType' (a nil value)

[Zango]

"getWeaponAmmoType" is not an MTA function but a custom one.

I'm guessing you found this script somewhere, you need the rest of it to make it work

if you want i can give you free airdrop system
