trouble changing a Vector3Value inside a character?

local debounce = false
script.Parent.Touched:Connect(function(hit)
	
	local value = hit.Parent:WaitForChild("HomePos")
	
	if hit.Parent:FindFirstChild("Humanoid") and value.Value == Vector3.new(0,0,0) then
		
	if not debounce then debounce = true
		local newpos = script.Parent.Parent.TpPoint
		
		value.Value = Vector3.new(newpos.Position)
	end
	end
end)

Im having trouble setting a vector3 values vector3 using a parts position. there are no errors and if I give it an x,y,z value it works fine but not if I use a parts position. I suspect im using this wrong, but dont be afraid to correct me.
