Why is this GUi working in studio, but not in game?

Alright, so I'm getting into GUi making for my new game. I spent a lot of time getting the effects and everything to work and run smoothly. After using play solo, it was perfect. But I went in game and it doesn't even detect my player clicking the SurfaceGui button. Another weird thing, after using test server in studio, the tab with my character cannot click it, but the other tab that overviews the server can. Pretty weird, right? Anyways, here's the code. (And there are two scripts, but the second is not relevant and doesn't change anything) EDIT: Forgot to mention, I have tried this in both Local and non local scripts. Local scripts didn't even work in play solo, so I turned it back to a regular script.

@TheDeadlyPanther After I added the prints and disabled/reenabled it. I got the following prints: 1,1 5 in that order

EDIT 2: Panther, after noticing you left chat and noticing you didn't get my messages.

right? ROBLOX Xoqex 4 Yes Once clicked, they should all show up So far I clicked play solo, I got 1,1,5 Now I will click and see Everything runs and I get 6 3 4 2 Testing in a server now Alright this is where it gets weird I have output in both server and player tabs of the test server The overview tab has 1,1,5, the player server has nothing. Clicked it in both windows, only the overviewing server tab worked. @TheDeadlyPanther
