DARKRP: I cannot OOC, Buy from Dealers Etc.

Hello,

Basically, on my Garry’s Mod DarkRP Server.
If I’m Gun Dealer and I wanna buy a Colt 1911
it Says, “/buy Colt 1911” and I don’t get my requested
Item. And when I type // (Message) it only says to people around me
“// (Message)”

First of all you need to make the cmd in the addentities.lua file cmd = /buycolt1911
Second stop editing DarkRP if you dont have some lua knowledge.
Three if you did not edit just download it from here : https://github.com/FPtje/DarkRP
