FCVAR_SERVER_CAN_EXECUTE prevented server running command: use

[masterbinkie]

So I'm developing a DarkRP server, and I added in custom Shipments for Gun Dealer.

Basically, all of them are working except for the AK-74 and the G36C (We are using FA:S SWEP pack), the actual buying the shipment works, but when they try to pick up the weapon (even buying a singular weapon) they get the error in their console that says "FCVAR_SERVER_CAN_EXECUTE prevented server running command: use"

I looked this up and saw several posts on it that mentioned CW (Customizable Weaponry) which is an addon that we use.

I want to try to fix this without removing FA:S, but if it's absolutely needed, I can, does anyone have a solution?
