(SOLVED) Why can't the script identify my character's Right Hand? [closed]

Is there a certain reason in the script for why it can't identify my character's Right Hand? in the line #9 weld.Part1 = char:WaitForChild("RightHand"), The Part0 in line #8 works fine; it can identify the weld's parent/handle but for the RightHand, it does not. This is on serverscript too tho.

 players.PlayerAdded:Connect(function(plr)
plr.CharacterAdded:Connect(function(char)
    local handle = handle:Clone()
    handle.Parent = char
    handle.Position = char:FindFirstChild("RightHand").Position + Vector3.new(0,-1.5,0.5)
    local weld = Instance.new("Weld")
    weld.Parent = handle
    weld.Part0 = handle
    weld.Part1 = char:WaitForChild("RightHand")
    end)
    end)
