Hector,
Thank you for helping me.
I am now able to see what the exception is.
I've made several adjustments to my program, but it's still not working.
I followed the example in the help system, but I keep getting the message,
"Update unable to find TableMapping['Table'] or DataTable 'Table'."

Do you have any idea why this is?

Rick

'----example from the help system --- "Updating the Database with a DataAdapter and the DataSet" ------

'catDA.Update(catDS)
