Default Chap 3 - Data From File

I feel like such an idiot, but I cannot get the example beginning on page 49 to work!

I have the csv file created by the previous step "Exporting Datra from Access" (pg 48), but when I carefully execute all the steps from pages 49 through 52, it doesn't work!

I get a successful build, but then ge the following error message:

"An unhandled exception of type 'System.NullReferenceException' occurred in ODBC Data Wizard 2.exe

Additional information: Object reference not set to an instance of an object."

The execution stops in the cboCompanies_SelectedIndexChanged subroutine, specifically, the "If" statement:
"For intIndex As Integer = 0 To CustomersDS1.Tables("Customer_csv").Rows.Count - 1"

What did I do wrong?
