Unreachable code

I do not understand why this portion of my code is considered "unreachable" by the compiler:


                  switch(type)
                                    {
                                          case("SelfEmployed"):return SelfEmployed;
                                                break;
                                          case("ActiveMilitary"):return ActiveMilitary;
                                                break;
                                          case("WorkForRelative"):return WorkForRelative;
                                                break;
                                          default:
                                                return 1;
                                                break;
                                    }
                  




Here is the function:



public int MPPQuestionsStatus(long tempEntryID, string TempConnectionString, string type)
                  {
                        string strTempSQL = "";

                        int SelfEmployed=0;
                        int ActiveMilitary=0;
                        int WorkForRelative=0;

                        string SelfEmployedRaw="";
                        string ActiveMilitaryRaw="";
                        string WorkForRelativeRaw="";



      
                        strTempSQL = "ShowMPPAnswers " + tempEntryID.ToString();
               
                        //Create DataSet
                        SqlConnection TempConnection = new SqlConnection(TempConnectionString);
                        SqlDataAdapter TempDataAdapter = new SqlDataAdapter(strTempSQL,TempConnection);
                        DataSet TempDataSet = new DataSet();
                        TempDataAdapter.Fill(TempDataSet, "Temp");
                        DataTable TempDataTable = TempDataSet.Tables["Temp"];
                        SqlCommandBuilder TempCmdBuilder = new SqlCommandBuilder(TempDataAdapter);                  

                        foreach (DataRow myDataRow in TempDataSet.Tables["Temp"].Rows)
                        {
                              try
                              {
                                    
                                    SelfEmployedRaw = myDataRow.IsNull("self-employed") ? "No" : myDataRow["self-employed"].ToString();
                                    ActiveMilitaryRaw = myDataRow.IsNull("Active Military") ? "No" : myDataRow["Active Military"].ToString();
                                    WorkForRelativeRaw = myDataRow.IsNull("work for relative") ? "No" : myDataRow["work for relative"].ToString();

                                    switch(SelfEmployedRaw)
                                    {
