Why wont this weld?

The script runs perfectly but it won't weld the part to the player...

UserInputService = game:GetService("UserInputService")
local player = game.Players.LocalPlayer

local function onInputBegan(input,gameProcessed)
    if input.UserInputType == Enum.UserInputType.Keyboard then
        local keyPressed = input.KeyCode
        print("A key is being pushed down! Key:",input.KeyCode)



    print('working')
print(input.KeyCode)

    if input.KeyCode == Enum.KeyCode.B  then
    x = script.BBall
    x:Clone().Parent = workspace
    local m = Instance.new('Weld', player.Character.Torso)
    m.Part0 = x
    m.Part1 = player.Character:WaitForChild('Torso')
    m.C1 = CFrame.fromEulerAnglesXYZ(0, 0, 0) *CFrame.new(0,-1.5, 0)

        print('Done')
    end
    end

end

UserInputService.InputBegan:connect(onInputBegan)
