Holy mother of swiss cheese. The problem that I'd been trying to track down the other week before getting the stats for January out? I'd named January's end date 1/31/2007 in the Jobs table, and 01/31/2007 in all the other tables. *facepalm* That is not so good for my ego.

Have called the car place & they'll be retrieving me. Hooray for cooperative car places.

Cleaned out the table that might have been causing another problem. 3/4 of the append queries for the month are done; it's that 4th one that's causing all the trouble.
