amazon isbn grab two fields

i am trying to make a tpl templtae that utlizes the amazon module. i cant figure out a way to grab two variables from it. right now if i grab the ISBN field..i can either get the product pic, a link, or a product pic and some details depending on how the field is set to display. I need to grab the pic, and just one aspect of the details (link to product). Anyone know how this is done..do i need to ISBN fields and just fill them with the same number and set them to different displays?
