Hi

I've been trying to develop a module using the video tutorial put on this site by seabury design, and the dnn 4x module template available in the starter kit on dotnetnuke.com.  Everything works fine until I reach the end of video 3.  I have followed all of the instructions given in the video, but when I try to add text to my blog module, and store it in the database i get the following message

Error: Edit First Module is currently unavailable.
DotNetNuke.Services.Exceptions.ModuleLoadException: Cannot insert the value NULL into column 'FirstID', table 'DotNetNukeDevelop.dbo.First'; column does not allow nulls. INSERT fails. The statement has been terminated. ---> System.Data.SqlClient.SqlException: Cannot insert the value NULL into column 'FirstID', table 'DotNetNukeDevelop.dbo.First'; column does not allow nulls.

Is there something I need to do that is not includded in the video.  I don't understand why my primary key firstID is being set to null

Thanks
