161145 Modify osCommerce Product Page

I have an osCommerce store using a purchased template. I have attempted to install a contribution that shows retail, our price, savings and it appears properly in my admin pages. However, my product listing page that my customers actually see does not display properly. I'm sure this is because of the template. I want to continue to use the template and need someone who can make the necessary modification. I have other small projects involving this same store will strongly consider the same person for a speedy job well done at a fair price.
