GUI issue

[cobalt quiver]

??

Why was it deleted I literally followed the format bruh

Image1:Code (loop part not working)
Image2:Example of GUI when I join
Image3:When I switch to stats then back to world

How it's supposed to work: Script checks if the buttons a certain color and that determines if the UI is visible or not, problem is that it doesn't start working until after I click off of it onto a different button then back to it. Script works just fine on tabs below which check for backgroundcolor3, while this is checking for imagecolor3. I've tried to fix by using a separate script just with the loop and it still doesn't work, yet no error outputs.
