Why is my script not working on the server?

This is my script. The script works on solo but not on server. My screengui is in playergui.

local winBoard = game.Workspace.Stationary.LobbyInternal.Jackel.SurfaceGui.TextLabel
local forest = game.ServerStorage.Maps["Forest Map"]
local plains = game.ServerStorage.Maps["The Great Plains"]
local snowy = game.ServerStorage.Maps["Snowy Life"]
local Maps = game.ServerStorage:WaitForChild("Maps"):GetChildren()
local ChosenMap = Maps[math.random(1, #Maps)]
local roundnumber = 0

Whereever it stops printing is where the problem is
	
the chat thing from my game is in the startergui
