The script is correct but the gamepass doesn't work ?

Hi, when i always make games i put gamepasses and follow YouTube videos But when i finish scripting the gamepass i always face error Like: When i click the gamepass button nothing appears like I didn’t do anything i always check twice to see if my script is like the the YouTube video and its the same and i put my gamepass number Help me please i want to do a gamepass script correct how?

first of all, dont copy what youtubers script, the trick is to UNDERSTAND it, then write it yourself. if you dont understand it, you dont know what the problem is. second of all, paste your script here and ill help you
