Hi guys, i working hard on a unity project. My Chat Script work in local game but it don't sent messages to other clients.Pls help im following this code import Debug;

 private var log:Array = new Array();
 private var dt = Date();
 var maxLogMessages:int = 200;
 var visible:boolean = true;
 var stringToEdit : String = "";
 var selectTextfield : boolean = true;
  var olay:int = 0 ;
 function Start() {
  
         Input.eatKeyPressOnTextFieldFocus = false;
         log.Add("Oyun içi Chat");
 }
  
 function print(string:String)
  
     {
  
         log.push(string);
         if(log.length > maxLogMessages)
             log.RemoveAt(0);
     }
  
     private var scrollPos:Vector2 = Vector2(0, 0);
     private var lastLogLen:int = 0;
     var printGUIStyle:GUIStyle;
     var maxLogLabelHeight:float = 100.0f;
  
 function OnGUI() {
     //
     
      var logBoxWidth:float = 180.0;
         var logBoxHeights:float[] = new float[log.length];
         var totalHeight:float = 0.0;
         var i:int = 0;
  
         for(var string:String in log) {
  
                 var logBoxHeight = Mathf.Min(maxLogLabelHeight, printGUIStyle.CalcHeight(GUIContent(string), logBoxWidth));
                 logBoxHeights[i++] = logBoxHeight;
                 totalHeight += logBoxHeight+10.0;
