So i am making a shop script for my server whilst also trying to learn functions. This is what i have done so far: https://pastebin.com/CvdS9gRw it used to just send the message if you couldn't afford it. Then i came back on after a while and it worked fully. Now (the next time i try it) nothing works what so ever. It displays the 64 stone and has the lore but when you click it nothing happens.
