David,

This one is very similar to the one you just did.  In fact, the data is almost identical.  We download power plant outage data from the California ISO website (manual until you guys get some free time to set up an automated scrape).  Anyway, the data gets into an Access database of mine in a table with key fields:  Date and Res Name.  The other fields include Type (planned or unplanned), Owner, Location, plant capacity, and of course, the quantity of the outage.  So, we need basically the large table as the one you did which lists each plant and the outage for "today" and let's say 1 week in the past.  We cannot go in the future because the data gets posted daily for that day only.  Then the other table will just summarize the total "Planned" and "Unplanned" by region.   A copy of the database is attached.  Let me know when you have a chance to start working on it.  Thanks.
