C# case statement issue

making an app for WP7 but have come across this case statement error. It appears on the 3rd case. Gives the "cannot fall through case error". I've googled this error and unless im not concentrating properly i'm sure i've set everything up correctly.

private void SortFeedData(int fs)
    {
        //only using cases 1,2,3 since 0 is for the news page which doesn't need sorting
        switch (fs)
        {
            case 1:
                //Sort feed data for "Scores" Page
                switch (ButtonSourceLeague)
                {
                    case "Premier League":
                        //clears all current feed data
                        App.Data.FeedList.Clear();
                        //For News Page - BBC Football RSS Feed

            }
            break; //Here's what you're missing.

In case 3: you don't have a break statement outside the inner switch. Therefore there is an implicit fall through to the next statement (even though there isn't a next statement).

The third case misses a break statement:

            break;
        case 3:

            switch (ButtonSourceClub)
            {

                case "Manchester United":

                    App.Data.FeedList.Add("rss xml link here");
                    break;
                default:
                    MessageBox.Show("Error");
                    break;
            }
            break; // <---- was missing
    }
