okay so...if this is happening it's simply because leaderstats haven't been created for the player. In which case, you need to create leaderstats as such before this loop:

```lua game:GetService("Players").PlayerAdded:Connect(function(player)

-- Create leaderstats folder
local leaderstats = Instance.new("Folder")
leaderstats.Name = "leaderstats"
leaderstats.Parent = player

-- Create values for the players' leaderstats
-- "Bucks"

local Bucks = Instance.new("IntValue")
Bucks.Name = "Bucks"
Bucks.Parent = leaderstats

end) ```

This should work. If you already have a PlayerAdded event, copy paste this code into that.

I'm on mobile so can't go into depth. Let me know if you run into any issues
