Great Job, Bob! I really appreciate your persistence with this. The query works just fine AND there will be some Null fields due to the guys only Clocking In or Clocking Out, but not both. So, your solution will cover that. I would like to ask one more thing. As you could see, this is an Access 2007 application. I've found '07 to be a little awkward to use. But you referenced a possible 'reference' issue. Can you refer me to something that should identify the references that I should have? Again, thanks so much for your help. I don't come here to often, but it's great that real professionals like you take time to work with the rest of us.
