script.Parent.MouseButton1Down:Connect(homeButtonClick)
function homeButtonClick ()
script.Parent.Parent.screen.BackgroundColor3 = Color3.new(252,0,9)
end
It is not working. Every time I click the button I get: attempt to call a nil value
Any fixes?

would you mind showing a picture of the explorer? attempt to call a nil value usually occurs when something doesn't seem to exist
