How to keep track of players leaderstats?

Ok so i made a leaderstats cash and the leaderstats is working correct but i want to take a track of the cash and when someone reaches 500,000 then it will print has alot of cash but it dosen't work here is the script i used:

game.Players.PlayerAdded:Connect(function(plr)
	if plr.leaderstats.Cash.Value == 500000 then
		print("has alot of cash")
	end
end)

if your wondering if my leaderstats script is correct and working then i want to tell you it works and i tested it and the following script is on server script service

Try this:

game.Players.PlayerAdded:Connect(function(player)
	local cash = player:WaitForChild("leaderstats"):WaitForChild("Cash")
	cash.Changed:Connect(function()
		if cash.Value >= 500000 then
			print(player.Name.." has a lot of cash")
		end
	end)
end)

Hello kind sir! I have just the thing!

game.Players.PlayerAdded:Connect(function(player)
    local cash = player:WaitForChild("leaderstats"):WaitForChild("Cash")--Finds the players cash
    if cash then--If the cash exists in the player then
	cash.Changed:Connect(function()--This runs every time the cash changes
        	if cash.Value >= 500000 then--If the players cash is large then do something
            		print(player.Name.." has a lot of cash")
			--Your code here!
        	end
    end)
    end
end)

This is simply a modification to the answer above. The Changed function detects whenever a value changes, so you can also use this for players in the server and stuff. I hope this helps you in your scripting journey! If you have any questions or concerns, comment below!
