How do I check for two blank boxes on a form

[Guest]

How can I check in the same procdeure two seperate field boxes on a form.

I have 3 boxes.

The first is a tick box. If the user ticks it. How can I ensure that he
fills in the two blank boxes associated with the tick box.

If the user doesn't tick the box, then the two text fields can remain blank.
I can do it with one text filed, but not two.

Help!

If IsNull(Me!NameOfFirstTextBox) And IsNull(Me!NameOfSecondTextBox) Then
...
End If
End If

Use the Before Update event procedure of the form to check if the other 2
boxes are Null when the check box is True.

Private Sub Form_BeforeUpdate(Cancel As Integer)
If Me.[Checkbox1].Value Then
If IsNull(Me.[Textbox1]) Or IsNull(Me.[Textbox2]) Then
Cancel = True
MsgBox "Must enter both values when boxes is checked."
End If
End If
End Sub

Guys,

Thanks for your help. My routine works to an extent. but assuming the
tick-box is 'Yes' it only checks if both fields are blank simultanesouly. The
problem is the user can fill-in one field but leave the other blank... any
ideas?

The code should force the user to enter both.

If you intended that the user must at least one (not necessarily both),
change the Or to an And:
If IsNull(Me.[Textbox1]) And IsNull(Me.[Textbox2]) Then
