	Inventory.PickupMessage "$GOTBACKPACK"
	States
	{
	Spawn:
		CMPK ABCDEFG 1 
		Loop
    Pickup:
        TNT1 A 0 A_GiveInventory("ShellBox", 1)
        TNT1 A 0 A_GiveInventory("ClipBox", 1)

Pickup:
TNT1 A 0 A_GiveInventory("ShellBox", 1)

The 'Pickup:' state should be used only for CustomInventory NOT for Inventory or BackpackItem.

Anyway you should either make ZScript custom Backpack OR make CustomInventory with ammo cap increasing via ACS smth like as:
'SetAmmoCapacity("<your_ammo_type>",GetAmmoCapacity("<your_ammo_type>")+<additional_cap_value_of_your_ammo_type>);' and with yours weapon upgrades, both into Pickup state.
