	Hi, My question - I want to make a report and want to select all fields with date null (fields not filled in/are empty). I tried {T_DossierMain.QuotDate} = Date (0, 0, 0) but get no records. Is it possible to select an not filled/empty field and if so how to do! Thanks for replay

	Again thanks for your reaction. I had played again and came to this formula: {T_DossierMain.QuotDate} = CDateTime (0, 0, 0) It works!!!!!! Till........

	I would have thought that will be bringing back the wrong data. That formula just converts the 0,0,0 to a date and then assigns it to the field. If you want to check to see which fields are null already and then return them then you need to put the formula i gave you in the record selection formula.

	I tried your way but no success. Again looking to the standard options – I tried {T_DossierMain.QuotDate} > Date (0, 0, 0) And also this works. Thanks again for your reaction. Till
