Ben,

You can also trap the values as they are entered

Private Sub TextBox1_Exit(ByVal Cancel As MSForms.ReturnBoolean)
With TextBox1
If Not IsDate(.Text) Then
MsgBox "Invalid date"
.SelStart = 0
.SelLength = Len(.Text)
.SetFocus
Cancel = True
End If
End With
End Sub

Private Sub TextBox1_KeyPress(ByVal KeyAscii As MSForms.ReturnInteger)
Select Case KeyAscii
Case 45 To 47 '/ - or .
Exit Sub
Case 48 To 57 'Nos 0 - 9
Exit Sub
Case Else
Application.EnableEvents = False
KeyAscii = 0
Application.EnableEvents = True
Beep
End Select

End Sub

Hi Ben,

Something like this may work for you:

With TextBox1
If Not IsDate(.Text) Then
MsgBox "Invalid date"
.SetFocus
.SelStart = 0
.SelLength = Len(.Text)
End If
End With
