How can I fix my dice tool not giving effects?

Hello!

I made a dice tool that gives you either bad or good boost

The lower the number, the bad the effect Is, and the higher the number, the good the effect Is

The problem Is that, when the tool Is activated the dice Is suppose to say the users name and give them a effect but Instead, says the humanoid name and won't give the effect, I also saw a error In output which says:

Humanoid is not a valid member of Backpack "Players.imnotaguest1121.Backpack"

Please help

Script:

local Tool = script.Parent
local Debounce = false

Tool.Activated:Connect(function()
	if not Debounce then
		Debounce = true
		local Dice = Tool.Handle:Clone()
		local VectorForce = Instance.new("VectorForce",Dice)

		Dice.Position = Tool.Handle.Position
		Dice.Orientation = Tool.Handle.Orientation
		Dice.CanCollide = true
		game:GetService("Debris"):AddItem(Dice,10)
