Saving and retrieving Adobe documents

I have Adobe Acrobat Professional 7.0 and Adobe designer 7.0. I have created static forms in Designer and want to use Acrbat to create and e-mail the forms to users to be filled out & saved using Acrobat Reader 7.0, saved and e-mailed back to me with their filled in information. I want to rename and save their individual forms so I can later send them via e-mail to a third person. Currently when I fill out one of the pdf forms I have created and save it, when I later retrieve it, the boxes are blank. When I highlite a box, it displays mutiple entries that have been made to that box. How can I save the filled out forms so when I retrieve it, it displays the information that was entered? Ken
