	Hello I am trying to figure out how to come up with code (within crystal 2016) that will only show students where the acceptance date is null. Hopefully, this will show me all students that are incomplete. Anyone know or have an idea how to do it? I can find all kinds of SQL statements; however, I am not sure how to do it in crystal. Les

	In the select expert, go to the formula editor and do a isnull check on the acceptance date (i.e., isnull({somedate}). Also make sure the "Default Values for Nulls" is selected in the Formula Workshop.

	Thank you, that is what I am looking for. What if I wanted to report on 2 blank fields, would it be an if statement or would I just put it in the select expert such as: ISNULL({Treatme2.AppUser}) and ISNULL({Treatme2.AppDate}) Treatme2 is the table. AppUser is the field. Edited by lbuffett - 19 Jun 2018 at 7:09am

	Looks correct to me. Don't forget about the "Default Values for Nulls"
