Login Button below add to cart

Hi
I'm using JFBConnect on my site and I would like to be able to add a "login with facebook" button below the add to cart button on my product page.
I assume I need to edit the front end CSS file but which part the file do I need to edit?
I have looked through the file a few times but can't see where.
I have some understanding of the code but limited so could you bear this in mind.

Thanks

Hi there,

You just have to edit the view you are using to display your product and add this tag {JFBCLogin}
For example, go in Dispay>Views and choose the product/show_defautl and add this code where you want it
