Script doesn't change camera, doesn't make other texbuttons visible and make themselves invisible?

Nothing in the following script works. Literally nothing. This is my game file (btw I dunno how to make clickable links) : Cameras :https://gyazo.com/f1800cf4a28fbe3ebba721a72b40d5b1 Gui: https://gyazo.com/9e75f6d39f5d21625661dfd2d5c64a9f Entire script (very long):
