Other ways to get a up to date leaderstats variable?

The problem i am facing is when I fire the event, the script will not work, this is down to the arguments I am passing, I am giving the value of the players spins, this is working up until the point where I need to add to the value, where it will stop, I don't know any other way i could get around this though, If anyone knows anything please help me out, thanks!

The fire script:

local t = true

script.Parent.Activated:Connect(function()
    if t == true then
    game.ReplicatedStorage.addevent:FireServer(game.Players.LocalPlayer.playerstats.addition.Value, game.Players.LocalPlayer.playerstats.multiplier.Value, game.Players.LocalPlayer.playerstats.MaxValue.Value, game.Players.LocalPlayer.leaderstats.Spins.Value)
    print("Fired")
end
end)


script.Parent.Activated:Connect(function()
    if t == true then wait(.0001)
         t = false
        wait(1)
        t = true

    end
end)

The receiving script (in server script service)

game.ReplicatedStorage.addevent.OnServerEvent:Connect(function(plr, add, multiply, max, spin)
print(add)
print(multiply)
print(max)

local gamepass = 8784518
local service = game:GetService("MarketplaceService")

    if spin < max 
    and service:UserOwnsGamePassAsync(plr.UserId, gamepass) then
        spin = spin + add*multiply*2  print("DoublePass Pay!")
        if spin > max then
            spin = max
        elseif spin > max then
                spin = max
    elseif service:UserOwnsGamePassAsync(plr.UserId, gamepass) == false then
            if spin < max then 
            spin = spin + add*multiply print("Normal Pay")
            if spin > max then
            spin = max
        end
        end
        end
            end
            end)
