Symphony.

I'm using Symphony 2.3 and I'm trying to filter a select box link field. I'm using a parameter value as the filter value. The filter values I'm using should match the @handle of the linked items. I get the following error message when I test...

loadXML():
    StartTag: invalid element name in Entity, line: 166
    /home/jeffstreet/webapps/jeffstreet_climbing/symphony/lib/toolkit/class.xsltprocess.php:135

and this error in the XML when I debug...
