Minty, using the information/guidance you provided, I was able to get the reports up and running the way I needed. Thank you. Pat, thank you for the response also. I will take a look at the example you provided and see if I can use it.You can format the input from your date control, in the same way as your Expr4 data:
So in your criteria use:
Format([forms]![Form1]![Text131],"mm/YYYY")
You could create a second text box on you form to display that after updating date control on your form if it would make it more intuitive for the end user.
