Saving Multiple Selections

Hi - Here is code block for same set of database table - update form, this time using the Data Assist Server Behaviors. Code block copied re. the update form feature.

so, in your previous post offering a workaround for allowing multiple options within a drop down list, how do we integrate this line:
<?php echo(isset($_POST['elementName'])?implode(", ", $_POST['elementName']):""); ?>

??

Thanks for your help.
