What I am trying to do is to sort my array so I can eventually output it to a print file, but I can't get it to sort. I can't find the error in my code, but I've been trying different methods to sort a string for about 2 hours. I can't use a predefined method for sorting (such as .sort from the array class), but I can't figure out why I keep getting this error. I know it's because I'm pointing somewhere I shouldn't, but I can't figure out why it's pointing there. I would be greatful for any help.
