Remote Event problem?

FireServer() won't work when I test it on a actual server The script that prints "shopp" is in workspace The other one is in a local script in some Guis.

shopPrev.PurchaseButton.MouseButton1Down:connect(function()
    print ("firing server")
    game.workspace.Test.Shop:FireServer()
    print ("firing server2")
end)

script.shop.OnServerEvent:connect(function(player)
    print("shoppp")
end)

Prints firing server and firing server2
