I am having trouble with some code for save and loading a high score. It saves the score and loads a score but it will NOT count past 9. I think it is a problem with having a single digit or a double digit number. I can change the score in the system.DocumentsDirectory and it will show in the high score
but will change when the players score is > then 1. I mean the high score will change to 2. For example I type in 13 for the high score and score 2 points playing the game and the high score will
change to 2. If the high score is <= 9 than the high score seems to work but only up to 9.
So is there something in the code that is preventing the numbers switching to double digits.
I think this code is from Peach Pellen
I would greatly appreciate any help.

The original code had *a on line 17 I changed it to *n it made no difference. I have no idea what the code between --ANSCA sample code-- is doing I know it is a table but I don't understand every line.
