- List of Node by Title - mysql_fetch_object() error...

Hi,
I'd like to display a list of node title in a combo box and then select an item from the list. I'm getting "mysql_fetch_object(): supplied argument is not a valid MYSQL result resource" error. Here is the code snippet; does anyone know what I'm doing wrong? Thanks for your help.

Page Title:

 $result = db_result(db_query("SELECT node.nid, node.title FROM node node WHERE node.type in ('Test') ORDER BY node.title ASC"));     
                        
while ($row = db_fetch_object($result)) 
{
      $value = $row["node_title"]; 
  content .= "<OPTION VALUE=" .$value. "><".$value."</OPTION>";

}
....
