Another Newbie With Text Field / Combo Box Form Question

I have to convert a document into a form that will need do the following:

Have a page (pageUserInput) that contains a text field in which users will enter their name (inputText1)

Next to that a combo box that will designate which category the user will fall into (UserA, UserB, UserC or UserD)

I then have additional pages that correspond to the categories (pageUserA, pageUserB, pageUserC, pageUserD) which will have text fields (textUserA, textUserB, textUserC, textUserD) that need to autopopulate with the user's name that was entered into the input text field (inputText1).

Those text fields (textUserA, textUserB, textUserC, textUserD) will need to autopopulate duplicate text fields, which, if I name the same, I understand, will happen automatically.

If possible could someone share with me the script necessary to accomplish this or point me to an example of how to accomplish this? Am I on the right track to accomplish this? Can a combo box trigger the autopopulation of the fields in this manner?

Oh this is all being done in Acrobat 8 Pro (only version I have access to).
Thank you all in advance!
