ASP.NET MVP 3 Validation error
===

If you go to this website, <http://www.asp.net/mvc/tutorials/getting-started-with-aspnet-mvc3/cs/intro-to-aspnet-mvc-3>, you can see a tutorial where users create a movie database. I completed this tutorial with no problems, and attempted to create a new MVC application with some small changes that make the project more similar to what I want to do eventually. 

Rather that create a model named Movie, I created one named Issue. Like movie, it has a few fields, but they are all different names and types. I went through the process exactly as is done in the tutorial, but whenever I try to add an issue to the database via the web UI, I get a DBEntityValidationException. I have not set any validation rules at this point in the process, so I am unsure of what the problem is. 

Can someone give me some advice on fixing this so that I can add Issues to my database (as is done with movies on the online tutorial)?
Let me know if more information is needed; I am very new to this and may be lacking in details.
