How do I edit this Buy button and Registration for

My friend has a site that the developer did not finish. It uses Hikashop and there is no instruction in how to edit the Buy button and the Registration form.

the site is www.socialseduction.com/gordoncowie

the page is Coaching and the product page is:
socialseduction.com/gordoncowie/index.ph...5&category_pathway=0

What I would like to do is change the "Buy" button to "Register" and to customize the form to reflect other data.

Please advise.
Thank you in advance.

That view is displayed by the file show of the view product that you can edit via the menu Display->Views.
This is not the standard product page and has been heavily customized so we won't be able to help you much further I'm afraid.

Thank you,
that did it. i appreciate your assistance.
