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)
