DarkRP Weapon shipment help!!

Hello! i just installed css_realistic_shipments_for_darkrp. I have done what the info told me to do but the weapons will not show up! is there something i missed when putin the addshipments.lua into my garrysmod/garrysmod/gamemodes/DarkRP/gamemode/addshipments.lua? please help!

Update-
I fixed the top problem but now i can spawn the shipments an the gun pops out of the box but it will not let me pick it up. Yes i have the latest ver of Darkrp and CSS installed

Update-
I fixed everything! i had to get css realistic 4 and use madcows addshipments.lua and then i used the addenitiys from realistic weapons!
