Help!!!!

I have a Word 2000 document that contains a dropdown field (Dropdown1). The dropdown has 'Item1', 'Item2', 'Other'. I also have a text box(TextBox1) in this document. I need the TextBox1 text box enabled if the dropdowns 'Other' is selected. For all other options (Item1 and Item2), I need the dropdown disabled, so that the user cannot type anything in this box.

Any help is appreciated.



Thanks in advance.
