Multiplayer - Using BroadCast in OnIncomingData function

Client code:

         Debug.Log("Client : " + data);
         string[] aData = data.Split('|');

         switch (aData[0])
         {
             case "SWHO":
                 Send("CWHO|" + clientName);
                 break;

Server code:

         Debug.Log("Server : " + data);
         string[] aData = data.Split('|');

         switch (aData[0])
         {
             case "CWHO":
                 c.clientName = aData[1];
                 BroadCast("SCNN|" + c.clientName, clients);
                 Debug.Log("I AM: " + clients[clients.Count - 1].clientName);
                 BroadCast("SNUM|" + c.clientName, clients[clients.Count - 1]);
                 break;
 
 

I don't build the project, I only sign as host.

The output is:

Client: SWHO|

Server: CWHO|Host

I AM: HOST

Client: SCNN|Host

What I expected is:

Client: SWHO|

Server: CWHO|Host

Client: SCNN|Host

I AM: HOST

Client: SNUM|Host

Why "SNUM|" doesn't come up ? I send the message to the last connected client so that's the host !?

Edit: If I write "BroadCast("SNUM|")" before "BroadCast("SCNN")" , "SNUM" comes up but "SCNN" doesn't come up.

Can't I call BroadCast two times ? ?
