What you need to do is create a proper form.
Create the document however you are comfortable with, but leave the areas that are to be filled in by the user empty. (to keep it neat, I would suggest using tables - you can change the colour to white later, so that they can't be seen.)
Then go to:
View >
Toolbars >
Forms - click this to bring up the
Forms toolbar
The first icon (
ab|) is a
text form field - use this to add fields wherever the user is to fill in information.
If you right-click on the field and look at the
properties you can set some of the properties, including 'length' (play around with the settings to get it the right length.)
Once you have finished - select the
table and change the line colour to
white, then click on the little padlock on the
Forms toolbar to protect the form - this means that users can now ONLY enter data into the fields, every other part of the document is locked.
If you now save this as a
template and put a link where the end user can double click it, that should cover all that your boss is looking for!
