Well, your weld doesn't have a Part0, so it isn't welding to anything. You also never parented it.
local w = Instance.new("Weld") w.Part1 = Player.Character:FindFirstChild("Right Leg") w.Part0 = -- Whatever you're trying to weld to the right leg. w.C0 = CFrame.new(-0.65, -0.25, 0) * CFrame.fromEulerAnglesXYZ(math.rad(25), 0, 0) w.C1 = CFrame.new() -- Also not sure why this line is here. w.Parent = -- Whatever you're trying to weld to the right leg
