Script changing a number to a random high didget number instead of 6?

I have a script that when u buy something ur money per second goes up, by +1 more than it originally was but its doing 80 instead of 6

When i buy the upgrade my persec will go from 5 to 6 then when i click it does a random high didget number around 80 or 100

money giver script

local clickable = true
script.Parent.Activated:Connect(function(plr)
    if clickable then
        clickable = false
local player = game.Players:GetPlayerFromCharacter(script.Parent.Parent)
        player.leaderstats.Money.Value = player.leaderstats.Money.Value + player.Upgrade.persec.Value
        player.leaderstats.Total.Value = player.leaderstats.Total.Value + 1
        wait(5)
        clickable = true
    end
end)

    if game.Players.LocalPlayer.leaderstats.Money.Value >= 100 then
