LeftHand is not a valid member of Model? Welding Problems

So when a player joins it should fire a client but in the client it says that i cannot find the left hand . This is server script

local replicatedstorage = game:GetService("ReplicatedStorage")

game.Players.PlayerAdded:Connect(function(plr)
    replicatedstorage.Remotes.JustARandomWeld:FireClient(plr)
end)        

Local Script

local replicatedstorage = game:GetService("ReplicatedStorage")
local gloves = replicatedstorage.Objects
local remote = replicatedstorage.Remotes.JustARandomWeld

remote.OnClientEvent:Connect(function(plr)
    local leftweld = Instance.new("Weld")
    local gloveleft = replicatedstorage.Objects.LeftArmGloves:Clone()
    gloveleft.Position = game.Players.LocalPlayer.Character.LeftLowerArm
    leftweld.C0 = game.Players.LocalPlayer.Character.LeftLowerArm
    leftweld.C1 = gloveleft.WeldPart
end)
