I just picked up the book today and I'm running through the examples. The datacontrolMDX example is blowing up on me saying invalid character on line 4. Here's my code...
<%@ import Namespace="System.Data" %>
<%@ import Namespace="System.Data.OleDb" %>
<script language = "vb" runat = "server" debug = "true">
sub page_load (Sender as object, E as EventArgs)
    Dim objConnectoin As OleDbConnection
    Dim objCommand As OleDbDataAdapter
    Dim strConnect As String
    Dim srCommond As String
    Dim DataSet1 As New DataSet
    strConnect="Provider=Microsoft.Jet.OLEDB.4.0;"
    strConnect += "Data Source=C:\BegASPNET11\grocertogo.mdb;"
    strConnect += "Persist Security Info=False"
    strCommand = "SELECT ProductName, UnitPrice FROM Products"
    objConnect = New OleDbConnection (strConnect)
    objCommand = New OleDbDataAdapter(strCommand, objConnection)
    objComman.Fill(DataSet1, "products")
    DataGrid1.DataSource=DataSet1.Tables("Products").D efaultView
    DataGrid1.DataBind()
End Sub


Here's the error...
Compiler Error Message: BC30037: Character is not valid.

Source Error:

The import statements must be at top, below the page declaration. They can't be in the script block.
