Position is not a valid member of BodyVelocity HELP??!

the script im using has an error and i dont know how to fix it :(

the script:

local remote = script.Parent
local firstmvDb = false
remote.OnServerEvent:Connect(function(Player,Action)

    local char = Player.Character
    local hum = char:WaitForChild("Humanoid")
    local humrp = char:WaitForChild("HumanoidRootPart")


    local Anims = script:WaitForChild("Anims")
    local Sounds = script:WaitForChild("Sounds")
    local FX = script:WaitForChild("FX")

    local Incoming = hum:LoadAnimation(Anims:WaitForChild("RaiselKick"))
    local HitKick = hum:LoadAnimation(Anims:WaitForChild("HitKick"))

    if Action == "FirstMove" then
        if firstmvDb == false then
        print("ACCION EJECUTADA")
            firstmvDb = true
            delay(4,function()
                firstmvDb = false
            end)
            Incoming:Play()

            local Pos = humrp.CFrame * CFrame.new(0,40,0)
            local BP = Instance.new("BodyVelocity",humrp)
            BP.MaxForce = Vector3.new(math.huge,math.huge,math.huge)
            BP.Position = Pos.p
            BP.D = 10
            BP.P = 50
            game.Debris:AddItem(BP,1)
        end
    end
end)
