While following Chapter 7, the following error occured:

"NullReferenceException was unhandled"
"Object reference not set to an instance of an object"

The error happened on the PersonalDetails.vb line 64 which reads:

"txtFirstName.Text = mPerson.FirstName"

Prompt reply would be appriciated.

Thanks!

What appears to have happened is that mPerson has not been initialized to an instance of the class. Can you tell me if you did this using the starter code for the chapter in the download or have you been working on the project right from the start of the book?

Also, if you could confirm which page number you're on, I can start to pinpoint where your code might be having the issue.

Thanks
