not recving/sending and errno = 0

This is my first time doing any sort of network programming
I have both a server and a client that can connect to each other, the client can send data to the server but not vice versa

server:

Code:

void Init_Network()
{
    if (WSAStartup(MAKEWORD(2,2), &WSAData) == SOCKET_ERROR)
        MessageBox(0, "ERROR", "ERROR", MB_OK);

    SockFD = socket(PF_INET, SOCK_STREAM, 0);
    if (SockFD == SOCKET_ERROR)
        MessageBox(0, "ERROR", "ERROR", MB_OK);

    memset(My_Addr.sin_zero, '\0', sizeof My_Addr.sin_zero);
    My_Addr.sin_family = AF_INET;
    My_Addr.sin_port = htons(Port_Number);
    My_Addr.sin_addr.s_addr = INADDR_ANY;

    if (bind(SockFD, (struct sockaddr *)&My_Addr, sizeof(struct sockaddr)) == SOCKET_ERROR)
        MessageBox(0, "ERROR", "ERROR", MB_OK);

    if (listen(SockFD, 5) == SOCKET_ERROR)
        MessageBox(0, "ERROR", "ERROR", MB_OK);
}

Code:

                //send
                OutMessage[0] = 'c';
                OutMessage[1] = MyPos.X;
                OutMessage[2] = MyPos.Y;
                OutMessage[3] = '\0';
                nBytes = send(SockFD, OutMessage, 20, 0);
                std::cout<<errno;
                memset(OutMessage, ' ', 20);

client:

Code:

void Init_Network()
{
    if (WSAStartup(MAKEWORD(2,2), &WSAData) == SOCKET_ERROR)
        MessageBox(0, "ERROR", "ERROR", MB_OK);

    SockFD = socket(PF_INET, SOCK_STREAM, 0);
    if (SockFD == SOCKET_ERROR)
        MessageBox(0, "ERROR", "ERROR", MB_OK);

    Host_Entry = gethostbyname(IP);
    if (Host_Entry == NULL)
        MessageBox(0, "ERROR", "ERROR", MB_OK);

    Server_Addr.sin_family = AF_INET;
    Server_Addr.sin_port = htons(Port_Number);
    Server_Addr.sin_addr.s_addr = *(unsigned long*)Host_Entry->h_addr;
}

Code:

                //recv
                EnemyPrevPos.X = EnemyPos.X;
                EnemyPrevPos.Y = EnemyPos.Y;
                error = recv(ServerFD, InMessage, 20, 0);
                if (error == 0)
                {
                    std::cout<<"Your opponent has left the game."<<std::endl;
                    return 0;
                }
                if (error == -1)
                {
                    char temps[50];
                    SetConsoleCursorPosition(hOut, tempC);
                    perror(temps);
                    std::cout<<temps<<std::endl;
                    std::cout<<errno<<std::endl;
                    //return 0;
                }
                switch (InMessage[0])
                {
                    case 'c':
                        EnemyPos.X = InMessage[1];
                        EnemyPos.Y = InMessage[2];
                        break;
                    default:
                        SetConsoleCursorPosition(hOut, tempC);
                        std::cout<<InMessage;
                        break;
                }
                memset(InMessage, ' ', sizeof InMessage);

oops, i passed the wrong FDs to the send and recv function...
