Help me activate my position save script?

I have these scripts here, and i want to activate them only by touching a part, so only if i touch a certain part the position saves. first script:

game.Players.PlayerAdded:Connect(function(player)
    local val = player:WaitForChild("Position")
    player.CharacterAdded:connect(function(char)
        while true do
            wait(1)
            val.Value = char:WaitForChild("HumanoidRootPart").Position
        end
    end)
end)

Second script:

local ds = game:GetService("DataStoreService")
local ds1 = ds:GetDataStore("PositionSAvingSystem")

game.Players.PlayerAdded:Connect(function(player)
    local val = Instance.new("Vector3Value",player)
    val.Name = "Position"

    local userdata
    pcall (function()
        userdata = ds1:GetAsync(player.UserId)
    end)

    if userdata then
        game.Workspace:WaitForChild(player.name):WaitForChild("HumanoidRootPart").CFrame = CFrame.new(userdata.x, userdata.y, userdata.z)
    else
        ds1:SetAsync(player.UserId, {
            x= 0,
            y= 3,
            z= 0
        })
    end
end)

game.Players.PlayerRemoving:Connect(function(player)
    ds1:SetAsync(player.UserId, {
        x = player.Position.Value.x,
        y = player.Position.Value.y,
        z = player.Position.Value.z

    })
    end)
