Search module php errors

[alexlr]

I've been tinkering with CMSMS for the past couple of weeks and just realized that I can't reindex my website.  Gives me this error:

Fatal error: Call to a member function TemplateId() on a non-object in /home/lawrenc1/public_html/cmsmadesimple/modules/Search/Search.module.php on line 408

Anyone know how I can fix this? According to Coda (my text editor) line 408 is:

            $dbresult =& $db->Execute( $q, array( 'template', $content->TemplateId() ));

I've changed all the template aliases; I have no idea if that's the problem.

Thank you for your help in advance.
