Parse error in this code...

[Tim Wheatley]

Parse error: parse error, unexpected T_LOGICAL_AND in /data/docs/racesimcentral.com/docs/forum/forumdisplay.php on line 641

PHP Code:

if ($thread[attach]>0) and $bbuserinfo['styleid']=17) {
        $paperclip="<img src=\"{imagesfolder}/paperclip.gif\" alt=\"$thread[attach] Attachment(s)\" border=\"0\" align=\"absmiddle\">";
     }
} else {
$paperclip="<img src=\"{imagesfolder}/paperclip2.gif\" alt=\"$thread[attach] Attachment(s)\" border=\"0\" align=\"absmiddle\">";
} 


Should the else be elsif?
