Cathy-- Since you don't want to make the bound table fields do the work, your best bet is to simply check the value of the fields before leaving the form. Your best bet is to attach the code to the form's BeforeUpdate event. An example follows: Private Sub Form_BeforeUpdate(Cancel As Integer) If Len(Me.txtRequiredFieldOne & "") = 0 Then MsgBox "Please fill in Field One", vbOKOnly + vbExclamation, "Can't Do That!" Me.txtRequiredFieldOne Cancel = True Me.Undo Exit Sub End If If Len(Me.txtRequiredFieldTwo & "") = 0 Then MsgBox "Please fill in Field Two", vbOKOnly + vbExclamation, "Can't Do That!" Me.txtRequiredFieldTwo Cancel = True Me.Undo Exit Sub End If If Len(Me.txtRequiredFieldThree & "") = 0 Then MsgBox "Please fill in Field Three", vbOKOnly + vbExclamation, "Can't Do That!" Me.txtRequiredFieldThree Cancel = True Me.Undo End If End Sub My example will work with a few fields, but if you've a whole bunch of fields to check, my code would get unwieldy and difficult to maintain; in such a case, you'd probably want to do something fancier. Let us know if you need more examples. This may be splitting hairs, but I just want to make sure you're covered: you stated, "...if 3 of the fields are null", rather than, "if any of the 3 fields are null". If by that you mean that you'd only want to prevent the form from closing if all 3 of the fields are null, your code could look like this: Private Sub Form_BeforeUpdate(Cancel As Integer) If Len(Me.txtRequiredFieldOne & "") + Len(Me.txtRequiredFieldTwo & "") + Len(Me.txtRequiredFieldThree & "") = 0 Then MsgBox "Please fill in the fields", vbOKOnly + vbExclamation, "Can't Do That!" Me.txtRequiredFieldOne Cancel = True Me.Undo End If End Sub Out of curiosity, what 'other problems' would be caused by setting the underlying table fields to not allow nulls? --Jim -----Original Message----- From: mso-bounce@xxxxxxxxxxxxx [mailto:mso-bounce@xxxxxxxxxxxxx] On Behalf Of Cathy.Evans@xxxxxxxxx Sent: Thursday, June 10, 2004 6:19 AM To: mso@xxxxxxxxxxxxx Subject: [mso] Access 2002: Checking For Nulls On Form Close Thought I'd recently seen some code to check for null values on form close, but not finding. I'm needing to do a check on form close that if 3 of the fields are null, a message will pop up telling user which field(s) need to be completed before closing. The form should not close till the data criteria has been met. Can't set the table field to required, that option caused other problems in my form, so I'm thinking the next option is to check the certain fields for null values before closing form. Any ideas?
