Dear Sir,
    I have suffered problem in electric trace. If user select downstream trace and select phase designation of ???AnySinglePhase??? from phase designation dropdown list and then perform trace. The return result get ???single phase??? as well as ???any phase??? features. I didn???t understand what the meaning of ???AnySinglePhase??? is. I have used below code for phase designation. Please give me explanation of above. Thanks in advance.

private mmPhasesToTrace GetPhasesToTrace(int phasesToTraceEnum)
            switch (phasesToTraceEnum)
                case 0:
                    return mmPhasesToTrace.mmPTT_Any;
                case 1:
                    return mmPhasesToTrace.mmPTT_A;
                case 2:
                    return mmPhasesToTrace.mmPTT_B;
                case 3:
                    return mmPhasesToTrace.mmPTT_C;
                case 4:
                    return mmPhasesToTrace.mmPTT_AB;
                case 5:
                    return mmPhasesToTrace.mmPTT_AC;
                case 6:
                    return mmPhasesToTrace.mmPTT_BC;
                case 7:
                    return mmPhasesToTrace.mmPTT_ABC;
                case 8:
                    return mmPhasesToTrace.mmPTT_AtLeastA;
                case 9:
                    return mmPhasesToTrace.mmPTT_AtLeastB;
                case 10:
                    return mmPhasesToTrace.mmPTT_AtLeastC;
                case 11:
                    return mmPhasesToTrace.mmPTT_AtLeastAB;
                case 12:
                    return mmPhasesToTrace.mmPTT_AtLeastAC;
                case 13:
                    return mmPhasesToTrace.mmPTT_AtLeastBC;
                case 14:
                    return mmPhasesToTrace.mmPTT_AnySinglePhase;
                case 15:
                    return mmPhasesToTrace.mmPTT_AnyTwoPhase;
                    return mmPhasesToTrace.mmPTT_Any;
