I create fill in forms all the time for our firm. (Word97)
1 - type the text
2 - Wherever you want people to type in answers put in a text form field (View, Toolbars, Forms, click first button for text form field).
(Sometimes I create a tablewith a form field for entry - depends on how much space is needed. You can also choose from different types of fields; you can set up default text; you can create prompts to help the user understand what should be put in the field; you can add yourown Help tips for people - such as, "To get from field to field in this form, hit TAB"
3 - when all fields are inserted, Protect the form
(Tools, Protect Document, Forms)
4 - save your document as a template (File Save As, depending on your firm's environment)
Note: Depending on the use of the form, I sometimes write code into the last form field to Unprotect the form, so if the users can edit the other text/modify as needed.
Hope this helps -
