I am trying to write code so that when the value entered
in a textbox does not meet certain criteria, the text in
the textbox is selected for correction by the user. Please
see the code below.

Once the user presses the tab key the message is displayed
but the focus is lost and goes on to the next textbox or
next frame if the textbox is the last one in the current
frame. I have tried before update and change as well as
exit. What am I doing wrong? How can I get it to go back
and highlight the textbox with incorrect text/value.
Thanks for your help.


Private Sub TextBox1_Exit(ByVal Cancel As
MSForms.ReturnBoolean)

If TextBox1.Value < 100 Then

msgbox "You must enter ....."

TextBox1.SetFocus
TextBox1.SelStart = 0
TextBox1.SelLength = Len(TextBox1.Text)

End Sub
