How do you get multiple OnServerInvoke functions to not break?

When I :InvokeServer() a RemoteFunction another script prints the player and the first two arguments but when I have another ModuleScript with an .OnServerInvoke() function it seems to break the previous script. Can anybody please explain why this happens?

The first script: function script.Parent.OnServerInvoke(player, nice, nice2) print(player.Name..nice..nice2) end
