How to make an event happen depending on a datastore value?

Hello, in my game, depending on which value the player has, 0-4, it unlocks a different level. When the first cutscene ends, it'll go to the level selection, and then use the script that detects the players leaderstats. As so here:

game.Players.PlayerAdded:Connect(function(coolguy)
        if coolguy.leaderstats.Cash.Value == 0 then
              --my code would go here.
        end
end)

Upon the script being ran (undisabled) when the player gets to the menu, it does nothing at all. (It's nothing wrong with the datastore.)

Any working answer is appreciated, thanks!

if a == 0 then --This only checks if the value is equal to 0 not above or equal to
if a > 0 then -- This checks if the value is above 0
if a >= 0 then -- This checks if the value is above 0 or equal to 0
