I've been trying to copy your code to my game and editing it so it would work with my game but it just doesnt do anything and I dont understand why
Send me some screenshots of what you're trying to do so maybe I can help you. I mean to do this better go into the https://forum.gdevelop.io/ and create a new thread.
sorry for not replying sooner when i originaly saw your message i didnt have time to make a thread and the next day i just forgot https://forum.gdevelop.io/t/im-folowing-this-tutorial-on-how-to-make-a-inventory...
