Location of Problem?

[rektitude88]

$topic_type="";

    if ($class->forum['use_topic_types'])
    {
        $topic_type = "<tr><td id='row1'>Topic Type</td><td id='row1' width='100%' valign='top'><select class='forminput' name='topic_type'><option value=''>---</option></select></td></tr>";
        $types = ";" . $class->forum['topic_types'] . ";";

        $Type_Array = explode(';',$types);

        foreach ($Type_Array AS $type)
        {
            if (trim($type)<>"")
            {
                $topic_type .= "<option value='".$type."'".($ibforums->input['topic_type']==$type ? ' checked' : '') . ">".$type."</option>";
            }
        }


        $topic_type .=  "</select></td></tr>";

    }

I'm trying to call $topic_type, but it keeps coming out blank.
The database is properly populated as well, so there must be a problem with that code.
Can someone see any obvious errors on my part?

just use some simple basic debug methods and you willl find any problem that may exist.
