[SOLVED] How do I get my GUI to be visible if my position is.. Help?

This is my code: https://gyazo.com/232887806e0ffe6bd48aca2ae807bf1a

Explaining: When TAB is pressed I want it to be visible (Tweening the position to the screen)..

Problem: But I want set so that if it is set to the position (1, 0, 0, 0) then it will run the code. But I don't know how to go through with if the position is this then it will do that.. Can anyone help?

Conclusion: I need help with the 4th line "if script.Parent.PlayerList.Position == (1, 0, 0, 0) then", something is wrong here.
