Thanks a lot for helping me! It is working really well.

When I close the document after entering something in the active x textbox, a popup comes with the message...
"parts of your document may include personal information that can't be removed by document inspector"

It can be disabled in Trust Center > Trust Center Settings > Privacy Options, but my question is - if I share this file to someone, is this pop-up comes every time they make any change to the textbox?? This may be annoying for them.
