There were six doors and there were two stings for each door one to open and one to close. We had to drill holes into the base and to stop the strings tangling we had to name each string on the base and thread each string attached to a door through with a needle. So six opening strings got put onto one handle and six closing strings onto the other handle. We had trouble with some of the doors opening and closing. We put metal eyelets on the base so the string didn't cut into the board.
