Yes, it's POSSIBLE. But it'll depend on how to design up your template
as to how it would work. So providing a lot of details would be
difficult.

Example...first you would have a checkbox or dropdown for the
question. If the user clicks or chooses YES, then you could either
have text that has been hidden and you could unhide it. But since
users can set hide/unhide settings on their own, you'd have to also
control the dialog box for that option...which can be done, but is
complex if you're not good with VBA.

So an alternative would be to insert bookmarks in various locations
and then create more of the form as AutoText. When an answer is YES,
you'd move to the bookmarked location for that answer and insert the
autotext that contains the rest of the form. Of you could also use
separate doc files with the "parts" and insert those into the needed
bookmarks.

I'd suggest you start by checking some of my free AutoForm tutorials.

You should probably start with the PLEASE FILL OUT THIS FORM series
(but skip # 5, that's advanced database connectivity).

But know that what you want to do will be a bit of a learning curve if
you don't know VBA.
