Hi Ray
To test this further I
Created a new site and opened one page.
I created a database, used MySql and tested the connection.
This was OK.
I created a record set as requested.
I selected DataAssistPages
In the wizard it shows
Results
Detail
and Insert Pages to be created
I did not select a preset and clicked finish to generate the pages.
When the wizard was Creating Details Page the error appeared
Regards
John
