[AccessD] Query result problem

Problem solved.
One of the source fields that was joined did not have any data before 5/1/2008.
Thanks for looking at it.

I'd guess that's it's the Date resrtiction combined with the INNER JOIN.

Are there any records with ProductionMonth values less than 4/1/2008 in 
[qry Injection Data for Oil and Gas Production Allocation]
