If Lantern is giving you an error message, you can't figure out how to structure a puzzle using functions and events, or just have a question about Lantern's programming syntax, please feel free to email me at evanw@tcdupage.org or evancwright@yahoo.com.  If you are getting an error message, please attach your XML project file and include a description of the problem.  I will run your project through the debugger and see what is going wrong.  Hopefully, this will lead to Lantern being just a little more user-friendly.
