After it was done i didnt see any bugs but when i asked my friend help me test it and he buy then wear weapon his weapon was invisible for me i thinked its a bug untill he told me my weapon is invisible too. I dont understand client siding so can someone help me with it? Here is the script(there is other scripts too so if it didnt comming from that script please tell me to post other) : wait() local TweenService = game:GetService("TweenService") local finish = workspace.ToolCams.Focus1.CFrame camera = workspace.CurrentCamera local timed = 0 local player = game.Players.LocalPlayer local char = nil finished = nil local Back = script.Parent.ScreenGui.Backward local For = script.Parent.ScreenGui.Forward local close = script.Parent.ScreenGui.Close local itemN = script.Parent.ScreenGui.ItemName local itemC = script.Parent.ScreenGui.ItemCost local Pur = script.Parent.ScreenGui.PurchaseButton local Debounce = false local tolv = false local tooly = nil repeat wait() until player.Character ~= nil --script.Parent.StatsGui.LocalScript.Disabled = false

while true do
    local Debounce = true
    local center = workspace.Center2
    local tool = game.Workspace.ToolTrigger
    if player.Character ~= nil then
    local char = player.Character
        local mag = (center.Position - char.UpperTorso.Position).magnitude
        if mag <= 6  then
            Get()
            Debounce = false
            start()
            Debounce = true

    end
end

wait() end Please help me ! i never used client sided and i dont know how to add/remove it D:
