My mouseEnter and mouseLeave isn't working?

I'm trying to get messages to pop that follow your mouse when you hover over a part. However the script only works in studio but in actual game. I have tried both local script and script.

function mouseEnter(player)
    print("enter")
    local mouse = player:GetMouse()
    player.PlayerGui.Messages.Messages["Remote1"].Position = UDim2.new(0, mouse.X, -.1, mouse.Y)

end

function mouseLeave(player)
    print("left")
    player.PlayerGui.Messages.Messages["Remote1"].Position = UDim2.new(1, 0, 1, 0)
end

script.Parent.ClickDetector.MouseHoverEnter:connect(mouseEnter)
script.Parent.ClickDetector.MouseHoverLeave:connect(mouseLeave)
