Javascript to save form in Acrobat X Pro

I have developed a return authorization form using the form function in Acrobat X Pro.  I would like to insert a "save" button into the form that would save the pdf form into a specific folder using the number field in the form as the file name.  I'm not much of a javascript programmer but wondering if anybody has done anything like this or is this possible?  If so, any guidance would be appreciated.

Thanks in advance,

Peter
