Private Message Delete Error

[Boofo]

g-force2k2, that fixed it. I knew I was doing something wrong but it didn't dawn on me what it was. The wierd thing is, the line I changed works fine in the following piece of code. Can you please explain to me why? This has me stumped now.

PHP Code:

if ($what=="move") {
    if ($allmsgs==1) {
        if (thisfolder!='') $thefolder=thisfolder; else $thefolder='0';
        $DB_site->query("UPDATE privatemessage SET folderid=".intval($folderid)." WHERE userid=$bbuserinfo[userid] AND folderid='$thefolder'");
    } else {
        if (is_array($privatemessage)) {
          while(list($key,$val)=each($privatemessage)) {
            $DB_site->query("UPDATE privatemessage SET folderid=".intval($folderid)." WHERE privatemessageid=".intval($key)." AND userid=$bbuserinfo[userid]");
          } //end while
        } else {
        eval("standarderror(\"".gettemplate("error_pmnoselected")."\");");
        exit;
        }
    }
