Change AET var to string, NameError to ValueError

Python was giving errors with TRUE as a bool, so I changed it to a string. Giving an undefined name returned a different error than I put in the except, so I edited it and ran some tests which were successful. I will work on implementing something to detect if the subreddit exists and if it includes anything (e.g. special characters) which cannot be in subreddit names.
