View with Comment fields throws errors

I created a view that displays the latest comment from a node in a list. The view throws the following error, but everything displays properly. I appreciate any help that can be offered with this, as the view seems to work right, it just throws this nasty error:

* warning: Invalid argument supplied for foreach() in C:\Web\Server\htdocs\d53\modules\node\node.module on line 521.
* warning: implode() [function.implode]: Bad arguments. in C:\Web\Server\htdocs\d53\modules\node\node.module on line 525.
* user warning: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1 query: SELECT n.nid, n.vid, n.type, n.status, n.created, n.changed, n.comment, n.promote, n.sticky, r.timestamp AS revision_timestamp, r.title, r.body, r.teaser, r.log, r.format, u.uid, u.name, u.picture, u.data FROM node n INNER JOIN users u ON u.uid = n.uid INNER JOIN node_revisions r ON r.vid = n.vid WHERE in C:\Web\Server\htdocs\d53\includes\database.mysql.inc on line 172.

This is the export of my view:
