Hoverboard is going wrong way when pressing w, a, s, d keys?

Server script:

local pps = game:GetService("ProximityPromptService")


local bp = Instance.new("BodyPosition")
bp.D = 1000
bp.MaxForce = Vector3.new(0, 0, 0)
bp.Parent = script.Parent

local bg = Instance.new("BodyGyro")
bg.MaxTorque = Vector3.new(0, 0, 0)
bg.Parent = script.Parent

pps.PromptTriggered:Connect(function(prompt, player)

    if prompt == script.Parent.ProximityPrompt then

        script.Parent:SetNetworkOwner(player)

        game.ReplicatedStorage.HoverboardRE:FireClient(player, script.Parent)

        bp.MaxForce = Vector3.new(math.huge, math.huge, math.huge)
        bg.MaxTorque = Vector3.new(math.huge, math.huge, math.huge)

        prompt.Enabled = false

        local character = player.Character

        character.Humanoid.WalkSpeed = 0


        local weld = Instance.new("Weld", script.Parent)

        weld.Part0 = script.Parent
        weld.Part1 = character.HumanoidRootPart

        weld.C0 = CFrame.new(0, (character.HumanoidRootPart.Size.Y * 0.5) + character.Humanoid.HipHeight, 0)
        weld.C0 *= CFrame.Angles(0, 1.2, 0)
    end
end)


game.ReplicatedStorage.HoverboardRE.OnServerEvent:Connect(function(player)

    if player == script.Parent:GetNetworkOwner() then

        script.Parent:SetNetworkOwner()

        bp.MaxForce = Vector3.new(0, 0, 0)
        bg.MaxTorque = Vector3.new(0, 0, 0)

        script.Parent.ProximityPrompt.Enabled = true

        script.Parent.Weld:Destroy()

        player.Character.Humanoid.WalkSpeed = 16

    end
end)
