Added Shipments won't show up in-game

First of all, please do not accuse me of being a shitty coder, this is my first attempt at producing something to do with DarkRP

I’ve added a custom shipment to the Medic class/team which sells the FA:S 2.0 First Aid Kit, I’ll provide an imgur link with the code just in-case I did something wrong.

It’s for single-player so yes I have downloaded the darkrpmodification addon, and have inserted the code into the right spot, I’ve restarted and in-game the Shipments tab is gray and cannot be clicked.

What my shipments.lua looks like
