Hi guys

This for a location and sub location dropdown box

The first box is populated from the database but what I want to do is populate the sub location box via cat_id box. This is all setup in the database
but i'm not quite sure why it isn't working

Any help I would be very thankful

PHP Code:
$quer2=mysql_query("SELECT DISTINCT location,cat_id FROM location order by location"); 
$quer=mysql_query("SELECT DISTINCT sublocation FROM sublocation where cat_id=$quer2 order by sublocation");


"obj.options[obj.options.length] = new Option('"$quer"','+1');\n";}
