Sorry, I missed that.
OK using that guys example, you need to create a new database connection to the MySQL information_schema database. Then create a recordset to look up the AUTO Increment ID for the table you will be inserting to:
SELECT AUTO_INCREMENT FROM information_schema.TABLES WHERE TABLE_SCHEMA = '<database name.' AND TABLE_NAME = '<table name>'
In the insert record behavior, bind the xID column to the AUTO_INCREMENT column in the recordset.
