You apparently tried to line this up with a proportionally spaced
font, and I fixed it. 

This is perfect structure for the tree tag:

     [tree  start=0
            table=??????
            master=parent_id
            subordinate=id
            autodetect=1
            spacing=4
            full=1]
        <tr>
        <td>
        [if-item-param mv_level]
                [item-calc]
                        return '&nbsp' x [item-param mv_spacing];
                [/item-calc]
        [/if-item-param]
        [item-param name]
        </td>
        <td>
                mv_level=[item-param mv_level],
                mv_increment=[item-param mv_increment],
                mv_children=[item-param mv_children]
        </td>
        </tr>
        [/tree]
        </table>

Save that data in a table and you are in business. See the messages about
the tree tag last week.
