IntValue not being updated?

So, I have leaderstats, and I did in a server script is add the points in but it wouldnt work? It doesnt even output any errors?

Code:

dumbellEvent.OnServerEvent:Connect(function(plr)
	local leaderstats = plr.leaderstats
	if leaderstats then
		local damage = leaderstats.Damage
		if damage then
			damage.Value = damage.Value +0.1
			print(damage.Value)
		end
	end
end)
