The problem with Pointshop

I tried to add a player model to my pointshop, and I followed the tutorial to the letter with no avail. It shows up on the list of player models when I’m in the server and there are no errors for anyone as I have already set up the FastDL. My problem is that it won’t let me buy the model I added; it asks me if I’m sure I want to buy it and when I click yes then nothing happens. I found that a few other people have had the same problem but I didn’t quite understand how they fixed it. This is my first time posting on Facepunch so I apologize if it’s in the wrong place or I formatted it incorrectly. I can post the code for the model if need be, although I’m not entirely sure where the error is.

This is for DarkRP, I’m hosting it off of my computer.

Thanks, PiRATE.
