Attempt to index nil with "Bucks" ?

So I was making a data store I got an error

"Attempt to index nil with Bucks"

Script:

	if success then
		jacobBucks.Value = player_data.Bucks
	end

	local player_data = {
		Bucks = player.leaderstats.Bucks.Value
	}

When initializing Bucks, try using WaitForChild, You most likely tried to access Bucks before it loaded, if you are trying to use the explorer for Bucks
