I am attempting to make a button that will only change on the screen of the player who interacts with it, however I am struggling to have the LocalScript actually recognize the part I need to be pressed

Here is the code

local part = game.Workspace:WaitForChild("Button"):WaitForChild("buttonPiece")

I get no error, but the part cannot be affected by any of my code

I expect this to allow the part to be referenced by the script, but that doesn’t happen.
