I don't know a whole lot about programming so excuse my messy code, but I'm working on a little choice-based game and my action listeners are throwing a nasty NullPointerException. Let me know what the issue might be. 

the error is 
Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException
with a continued list of (Unknown Source) based lines
