error with getch() in arrow key menu

Hello, I've been searching for a way to get arrow keys for a menu in a program im writing well, last night I figured it out, But there is still one problem, I need to be able to read the enter key as to select an option from the menu as follows:

pawns:
    int pawn;
    system("cls");
    pawndd:
    gotoxy(0,0);
       SetConsoleTextAttribute(hColor,455);
    cout<<"  RETURN TO PREVIOUS MENU";
    SetConsoleTextAttribute(hColor,23);
    cout<<"\n";
    cout<<"  INTEREST CALCULATOR";
    cout<<"\n";
    cout<<"  RENEW, EXTEND, OR REDEEM";
    //cin>>pawn;

kbmain=_getch();



      /*if(kbmain!='\0')
        {
            kbmain=_getch();
        }
        */


        kbmain=getch();



    if(kbmain == 'H')
    {
        goto hrer;
    }

    if(kbmain == 'P')
    {
        hintcalc:
    gotoxy(0,0);
    cout<<"  RETURN TO PREVIOUS MENU";
    cout<<"\n";
    SetConsoleTextAttribute(hColor,455);
    cout<<"  INTEREST CALCULATOR";
    SetConsoleTextAttribute(hColor,23);
    cout<<"\n  RENEW, EXTEND, OR REDEEM";
    cout<<"\n";

    }

    kbmain2=_getch();

      if(kbmain2!='\0')
        {
            kbmain2=_getch();
        }
         if(kbmain2 == 'H')
    {
        goto pawndd;
    }
        if(kbmain2=='P')
        {
            hrer:
                gotoxy(0,0);
    cout<<"  RETURN TO PREVIOUS MENU";
    cout<<"\n";
    SetConsoleTextAttribute(hColor,23);
    cout<<"  INTEREST CALCULATOR";
    SetConsoleTextAttribute(hColor,455);
    cout<<"\n";
    gotoxy(0,2);
    cout<<"  RENEW, EXTEND, OR REDEEM";
    SetConsoleTextAttribute(hColor,23);


        }
            kbmain3=_getch();

      if(kbmain3!='\0')
        {
            kbmain3=_getch();
        }
         if(kbmain3=='H')
        {
            goto hintcalc;
        }
         if(kbmain3=='P')
        {
            goto pawndd;
        }
