Hi Paul

You can use the exit event like this.
It will not leave the textbox untill the textbox is a date

Private Sub TextBox1_Exit(ByVal Cancel As MSForms.ReturnBoolean)
If Not IsDate(TextBox1.Text) Then
MsgBox "not a date"
Cancel = True
End If
End Sub

I'm using a userform with a textbox among other things. I
want to ensure that not only does the user submit a date
in that textbox, I want to make sure it is a valid date.
If the date is invalid, I want to display a warning
message.

Thanks for the help.

Paul
