My cash value is suppose to go up every minute but its not. (Roblox Studio lua error)

I was trying to re-edit the code over and over again but it still didn't work I've created the folder leader stats and when I play the game it shows that it's a part of the player. It says however that it isn't a valid member.

The other error says: Cash is not a valid member of Folder "Players.(players name).leaderstats"
