Try something like this:
DCOUNT("*", "Expediting", "(((Expediting.CompanyName)="ABM Commerical") AND ((Expediting.Requested)="OEM Print:B - Wendy Wright") AND ((Expediting.DateSubmitted) Between [Forms]![Expediting Report Range]![Text6] And [forms]![Expediting Report Range]![Text10]))")
I think you'll have to have this form open - Expediting Report Range.
Are the other queries the same? What table/query are they based on?
