I have a query that is made up of two tables. They are joined use the field "Part Number". I have 5 columns Sales Order, Part Number, Work Center, Date, Delivery. I have it setup with a criteria on the date field using < Date()+10 This works but it only returns values where there is data in every field. I know there are rows that have data in every column except work center but those are omitted. I have tried IsNull Is Null ="" like "" and a few others that didn't work either. All I am trying to do is return the rows of data where work center is blank. Thanks in advanced.
