OK I've deleted the value completely ('foreign' is not included in the form so I shouldn't have had it in the rs to begin with. Uploaded the page and still get a blank page. One thing that is curious: when I double-click on the MySQLi Update Record server behavior, I now get a message that says "It appears that one of your server-side values is improperly coded. Please check this interface for inconsistencies." I have no idea what this means or why it is showing up now.
