How to add a check/query a client if they have brought a PointShop item

So I am currently hosting a TTT server and I need to add a check to the Jihad Bomb to see if they have brought a certain PointShop item.
I am using _Undefined’s PointShop for Garry’s Mod 13 (http://www.facepunch.com/showthread.php?t=1228438)
Thank for the help!

Have you tried posting in the thread and asking _Undefined?

He’s banned. And so is Matt :confused:

Like what ms333 said, both developers are banned and I think I would reach more people posting it in a sub forum rather than a thread.

Worse comes to worse… you read through the lua like anyone else would and see if there is a function/make your own
