Now, if you don’t have it in your template, I suggest you copy the app/design/frontend/base/default/template/review/helper/short_summary.phtml file to app/design/frontend/default/your_template/template/review/helper/ folder because it’s a good habit to keep all override files together in your template folder, or you can just edit the file directly.
Now copy and paste this, which is the same file but with an extra div container and “no-rating” changed to “ratings”:
Your template is different than mine, so there might be some variation in spacing and whatnot, so send me a link and I’ll try to help as best I can. FYI, there won’t be a “0 Reviews”, there will be a “Be a first to review…” instead. Best I can do for now.
