uNet sync issue - Beginner's problem

Hi everbody,

I'm new to uNet and I'm having problems with syncing variables to the host. I have updated Unity to the latest patch, followed the UNET tutorial and read the documentation, but I'm sure something slipped by and I haven't gotten this code to run. I'm trying to get both the host and a client to control a single variable.

The code is very simple, every time I do a right click the value is increased by 1; when I do a left click it should be synced up. Here's the code

 using UnityEngine;
 using UnityEngine.Networking;
 using System.Collections;
 
 public class NetworkTestScript : NetworkBehaviour {
     
     [SyncVar(hook = "HookTest1")] 
     private int testValue1;

    // I just use this variable to make the sync variables visible in the inspector
     public int showTest1;
     public int myValue;
 
     // initializing with some number
     void Awake()
     {
         testValue1 = -90000;
     }
 
     // the controls
     void Update()
     {
         if (isLocalPlayer) {
             if (Input.GetMouseButtonUp (0)) {
                 UpdateTheData();
             }
             if(Input.GetMouseButtonUp(1))
             {
                 myValue ++;
             }
         }
 
         showTest1 = testValue1;
     }
 
     void UpdateTheData()
     {
         TransmitValue ();
     }
     
     [Command]
     void CmdGiveStringToServer(int _myVal)
     {
         Debug.Log (" my name is "+name+ " I am the Server: "+ isServer+" I am local: "+ isLocalPlayer +" the value recieved is "+ _myVal);
         testValue1 = _myVal;
 
         Debug.Log ("Values are now "+ testValue1);
     }
     
     [ClientCallback]
     void TransmitValue()
     {
         Debug.Log ("Transmitting from "+ name +" the value of "+ myValue);
         CmdGiveStringToServer( myValue);
     }
 
     //this just lets me know when it was modified.
     void HookTest1(int _var)
     {
         Debug.Log ("the test1 variable has been synced to "+ _var);
     }
 }

However, even after the hook is activated, the value in the server does not change while this appeared in the command line, the inspector still showed a value of 2.

when I tried updating the value from the client this happened:

Notice how both objects say they are the server. The value updated but only in that object, not syncing with the host. Likewise, when I change the value of the host, it does not change in the client.

I know I must be forgetting something really simple, but I can't place a finger on it. Do you guys know what I might be doing wrong?
