Why the server couldn't find Players?

Why the server keeps saying this (2) when I already set the value(1)? (IT WORKS AT STUDIO, BUT NOT AT ROBLOX ;-;)

(1) ServerScriptService.LoadMapScript:9: attempt to index global 'LocalPlayer' (a nil value)

(2) "Players" setting script

Players = game:GetService("Players").LocalPlayer

Error script part

PlayerGui = Players.PlayerGui

Others: Whole script

win.Value = 2
