Why won't the sound play when all buzzers have been pushed?

There are 4 buzzers, and I put both of these scripts in each buzzer and none of them work;

I am also getting no errors in the output.

Script 1:

local button = script.Parent
local sound = game.Workspace.AGTDesk.GB.GoldenBuzzer
local X1 = game.Workspace.AGTDesk.X1
local X2 = game.Workspace.AGTDesk.X2
local X3 = game.Workspace.AGTDesk.X3
local X4 = game.Workspace.AGTDesk.X4
local color = BrickColor.new("Really red")

if X1.BrickColor == color and X2.BrickColor == color and X3.BrickColor == color and X4.BrickColor == color then
	sound:Play()
end

Script 2:

local button = script.Parent
local sound = game.Workspace.AGTDesk.GB.GoldenBuzzer
local X1 = game.Workspace.AGTDesk.X1
local X2 = game.Workspace.AGTDesk.X2
local X3 = game.Workspace.AGTDesk.X3
local X4 = game.Workspace.AGTDesk.X4
local color = BrickColor.new("Really red")

function buttonClick()
	if X1.BrickColor == "Really Red" and X2.BrickColor == "Really Red" and X3.BrickColor == "Really Red" and X4.BrickColor == "Really Red" then
		sound:Play()
	end
		
end

button.ClickDetector.MouseClick:Connect(buttonClick())

Try this:

	local button = script.Parent
	local sound = game.Workspace.AGTDesk.GB.GoldenBuzzer
	local X1 = game.Workspace.AGTDesk.X1
	local X2 = game.Workspace.AGTDesk.X2
	local X3 = game.Workspace.AGTDesk.X3
	local X4 = game.Workspace.AGTDesk.X4
	local color = BrickColor.new("Really red")
	function check() 
	if X1.BrickColor == color and X2.BrickColor == color and X3.BrickColor == color and X4.BrickColor == color then
	    sound:Play()
	end end
    while true do
   check()
  print("loop") -- not needed, but its to check if the loop is working
 wait(0.5)
   end

Hope I got it all correct, best hopes for you!
