Thanks for the quick reply Jason
I get this if I create a brand new page and go straight to Webassist>MySQLi>MySQLi Recordset.
The Recordset dialogue box opens in advanced mode and pressing the 'Simple' button gives the error/warning - even before I've added any SQL query (screenshot attached).
I realise that once adding a more complex query that I can't go back to the simple dialogue box.
Cheers,
Dylan.
