Sean, you may not be there today but I made an interesting discovery. I tried four groupings for totals. For example, I took the group represented by:

Select *

From VehiclesToUpdate

Where Region='Central' And ProgYear='13' And RiskNonriskFlag='R' And MFG = 'MIT' And LeaseCycle='1' And ModelName='LANCER'

...and I got 202 units. Then taking that same grouping I tried adding the UnitCount in the RetrunsPros. Guess what. 202 units. I tried this for three other groups and they all matched perfectly. Then I tried it for the total unit count and they didn't match, but that could be explained by the gap cars (source='G') I'm getting closer. I thought you would like to hear the good news.
