NEWBY! Need help with Javascript to auto-populate pdf form...

I am new to Adobe Acrobat. I am using Acrobat 8, professional.
I need the action of choosing an option from a combo box to automatically populate other areas of the form with different information. Here is the exact examply i am trying to figure out:
Combo Box:
Degree Program: [select from a list]

this selection (ex. Humanities) will then populate 2 different areas:
1. Tuition text boxes (include: Tution, Health Service Fee, Activities Fee, etc. - about 7 fields, all will have different values)
2. address text box - will state the address of the specific degree program they first chose.

Can this be done? If so, HOW! if you can tell me exactly, PERFECT, if not, please refer to references.. or tell me - this is java, javascript, a function available in acrobat, etc.

THANKS!
Christine
