I am using an unbound form with various unbound text boxes as the source for a query's criteria. One of the optional unbound text boxes is a beginning date and an ending date for one field on the query. I am using the Between [beginning date] And [ending date] format as criteria for this particular field. If the user leaves these date text boxes blank on the form the query returns no records. I am familiar with using the Like "*" & format for text fields. Is there a similar way to handle the Between format so that if text boxes are left blank the query will return all dates for this field?
