Tini -
It certainly is possible, if I understand your description. It will
take you a little while to learn the details, but from Excel you can
open a Word document, and move to the place where you want the user to
type. If there's no exchange of information between the applications, I
wonder if you could do it more easily from a Word document, and maybe
use a hyperlink to a bookmark in the target document.
I have a few notes and examples of the use of Excel with other Office
applications on my web site. This page doesn't show what you want, but
it might be a good place to start. You could also try google with the
key words Excel Word Automation, and get lots more examples.
