Hi guys, i'm trying to make a shop with skript... All works well but i can't figure out how to do a: "add 1" in the shop. I don't know if you understood. Like, you type /shop, you click on "blocks" and you click on "grass block" and it opens a gui where there are a list of glass panes that adds blocks and price, like i want to add 64 of grass, i click on an item and i have it. I hope you understood, Thank you!
