I do not understand this problem.  I have it copied correctly.  See attached.[embed=file 5661.  This is homework.  I am sorry for posting more than one question.  I need to prepare this program completely then I have use it for a project.  I am sorry for the confusion.

Your dbConnection is first declared inside an if block so in line 37 it is not available to you. Declare it outside of the if block.

The book page does not show that part.

Like this:
protected void Page_LoadComplete(object sender, EventArgs e)
        {
            SqlConnection dbConnection;
            if (Page.IsPostBack && enrollmentForm.ActiveViewIndex == 3)
            {
                dbConnection
                    = new SqlConnection(
                        "Data Source=.\\SQLEXPRESS; AttachDbFilename=C:\\Course Technology\\CIS Programming\\ASP .NET Programming\\Data Files\\Chapter.09\\Chapter\\SkywardAviation.mdf; Integrated Security=True; User Instance=True");
            }
            try
            {
                dbConnection.Open();
