I don't currently run opensuse but I have in the past. I used zypper as the tool to manage packages and repositories. Even though I don't use opensuse I know enough to help the OP with his problem. If the OP didn't want to use the methods suggested to him that is fine, he could have simply said "Thanks for the info. I looked it over and still doesn't make sense to me. I am uncomfortable using the terminal for such things could you provide me a GUI solution to my problem?". Had the OP done that I would have gladly let someone more adept with Yast provide him an answer or pointed him to documentation on Yast.
So again I'm not trying to teach the OP I am trying to help him.
