How Do I Make A Notification That Prompts GamePasses?

Hey, gamingwithjbthepro!

I'm going to be attempting to fix the problem that you're having. I apologize that nobody hasn't helped you yet; most people may be busy and unable to help. Anyway, enough talking, let's get into the coding.

The only problem that I can notice, by reviewing your code, is that you didn't do the function correctly for the callback. No worries, you did everything else correctly! I will give you a Local Script that belongs in StarterPlayerScripts, and hopefully, this script can help you add more id's, if needed, and be much easier for you in general.

In the script, you'll see a table that is named "gamepasses." In this table, you'll see more tables that contain an id, title, and desc index. The id should be set to the gamepass id, the title should be set to the title of the notification, and the desc should be set to the notification text. You can add more tables by copying one of the two and just pasting it in and editing it to your needs.

That is the only thing that really needs to be covered since everything else is basically the same. If you have any questions, feel free to reply, and I'll answer them when I get the chance!

See ya around!
