This is exactly what I did:
* I created a recordset and a form (POST) for updating a mysql table and bound the field names to the recordset fields.
* Then I added a checkbox in the form and added a name and id to it.
* Next I added DA's repeat behaviour within the form for multiple action. with the submit button outside the repeat area but within the form
* Next I applied DA "update multiple" and started to bind the form fields. I realized that the behaviour not only added "_<?php echo $RepeatSelectionCounter_1; ?>" to each field's name and id but also to the checkbox (which I wanted to use for the multiple delete behaviour).
Is it better to apply the delete behaviour first?
