I realize that to fix this you are going to have to set each variable like E_Chest to an array so that you have one for each player. Using the same variable will cause problems with which player is using what. So do to each variable and set them to an array of size 2. Then fix every item for player 1s items to E_Chest (1) and player 2s to E_Chest (2). I hope that works. If not I'll make you a better version of the system that works with 2 players. Good Luck!
