URGENT: Error in the simulation

[Ribhu Majumder]

Hi,
I am creating a new simulation in OMNET PP where there is a home node which will create a message and send it to other nodes and after the message come back to its home node it will get updated.The network look like this:\

But I am having error in the simulation:

Here is my code  of the ned:
simple Sample2
{
    parameters:
        @signal[arrival](type="long");
        @statistic[hopCount](title="hop count"; source="arrival"; record=vector,stats; interpolationmode=none);

        @display("i=block/routing");
    gates:
        inout gate[];
}
//
// TODO documentation
//
network Network
{
    submodules:
        sample2: Sample2 {
            @display("p=6.742423,12.994488");
        }
        sample1: Sample2 {
            @display("p=12.38154,12.38154");
        }
        sample3: Sample2 {
            @display("p=9.185308,17.855553");
        }
        sample4: Sample2 {
            @display("p=5.236484,17.340488");
        }
        sample5: Sample2 {
            @display("p=0.90136206,13.30582");
        }
        sample6: Sample2 {
            @display("p=1.9744121,7.468428");
        }
        sample7: Sample2 {
            @display("p=6.9104424,6.180768");
        }
    connections:
        sample2.gate++ <--> sample1.gate++;
        sample2.gate++ <--> sample3.gate++;
        sample2.gate++ <--> sample4.gate++;
        sample5.gate++ <--> sample2.gate++;
        sample6.gate++ <--> sample2.gate++;
        sample7.gate++ <--> sample2.gate++;
        sample6.gate++ <--> sample7.gate++;
        sample7.gate++ <--> sample1.gate++;
        sample1.gate++ <--> sample3.gate++;
        sample3.gate++ <--> sample4.gate++;
        sample4.gate++ <--> sample5.gate++;
        sample5.gate++ <--> sample6.gate++;
}

The main code in C++:
/*
 * Sample2.cc
 *
 *  Created on: Jun 27, 2016

 */

#include <string.h>
#include <omnetpp.h>

using namespace omnetpp;

class Sample2 : public cSimpleModule
{

    bool homeNode = false;

    int cont = 0;

  protected:
    virtual void initialize() override;
    virtual void handleMessage(cMessage *msg) override;
};

Define_Module(Sample2);

void Sample2::initialize()
{
    if (strcmp("sample2", getName()) == 0) {
        // The `ev' object works like `cout' in C++.
        EV << "Sending initial message\n";

        homeNode = true;
        cMessage *msg = new cMessage("Subhrajit");
        send(msg, "inout");
    }
}

void Sample2::handleMessage(cMessage *msg)
{

    if (homeNode)

    {

          // do something

          cont++;

          msg->setName("abcd");
    }
    // msg->getName() is name of the msg object, here it will be "tictocMsg".
    EV << "Received message `" << msg->getName() << "', sending it out again\n";
    send(msg, "inout");
}


Please help me anyone.

Your gate's name is "gate" not "inout" inout is the TYPE of the gate, so your send should be:

send(msg, "gate");

additionally you have a gate VECTOR so you should specify in the send call the index of the gate you want to use
