I have a table with about 9 fields, and record ID field an
agency name field and the # of gallons that a erson pledges to save:
-- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- --
|ID| agency| 5g | 8g | 10g | 12g | 15g | 18g | 20g |
-- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---- ---

Each of the gallon fields are either a 0 or  the # of gallons for that
column:
|1 | Helix | 0 | 8 | 10 |  0  | 15 |  0  |  0 |
|2 | corp  | 5 | 8 |   0 | 12 | 15 | 18 | 20 |
|3 | Helix | 5 | 8 | 10 |  0  | 15 |  0  | 20 |
|4 | Helix | 5 | 8 | 10 |  0  | 15 |  0  |  0 |
|5 | corp  | 5 | 0 |   0 | 12 | 15 |   0 | 20 |

I need to be able to obtain the top 5 pledges per agency:
| Helix |8g = 3|10g =3 |15g = 3 |5g = 2 |20g = 2 |
| Corp |5g = 2 | 12g = 2 |15g = 2 | 20g = 2| 8g = 1|

Thanks,

Nestor :-)
