Question Details:

I have a business form that I created in word and made into a PDF file. I need to make it where I can email the PDF file to someone and they fill in the form when they open the file.

Answer:

PDF fill-in form documents are PDF documents which include spaces where you can type to fill in the form. Will only work in the latest versions of Acrobat.

You can find here a tutorial on how to create fill in forms.
