Simple sending data between client/server - unity3d

Question

I am trying to send data on a simple multiplayer game, using Var1 and Var2 in this example. Var1 should sent and be stored as Var2 in the other user's instance.
The code I have sort of works, except I think the server is sending data to itself and overriding the data it receives, because if I load the client and initialize/send data, the server sees it. Then if I go to the server and initialize/send data, the client sees it. But if I go back to the client and send data, the server no longer sees it. It's like the server is acting as both a client and a server. Am I doing something wrong somewhere?
public class mouseController : NetworkBehaviour
{
GameLoop g;
void Start()
{
GameObject thePlayer = GameObject.Find("Main Camera");
g = thePlayer.GetComponent<GameLoop>();
}
void Update()
{
if (!isLocalPlayer)
{
return;
}
if (isServer)
{
if (g.var1 > 0)
{
Rpcsenddata(g.var1);
}
}
else
{
if (g.var1 > 0)
{
Cmdsenddata(g.var1);
}
}
}
[Command]
void Cmdsenddata(int i)
{
g.var2 = i;
}
[ClientRpc]
public void Rpcsenddata(int i)
{
g.var2 = i;
}
}

(the data being sent is the card selected by your opponent. The server is the window on the right)

Answer 1

I think I fixed it by adding a !isLocalPlayer check
[ClientRpc]
public void Rpcsenddata(int i)
{
if (!isLocalPlayer) {
g.ehandSelected = i;
}
}
