Textbox's by default don't have perquisites.
Based on PM:
You have this
[php]
If Textbox1.text = "Whatever they want" Then
Me.hide
Form2.show
End If
[/php]
If you want form2 to show and the active form to hide, Ignore the textbox all together. it's just
Under Button Click event
[php]
Me.hide
Form2.show
[/php]
