Activating object layers basing on document layers

Hello,

I have a series of Illustrator files placed on different layers in an Indesign document.

I would like to set the visibility of the layers contained in the Illustrator files basing on the name of the Indesign layers to which they belong (Eg.: I want to activate only the "ES", "quote", and "disegno" layers in my Illustrator file if this one is on the "ES" layer of my Indesign file).

Here is my first attempt (which gives me an error):

var myDoc = app.activeDocument;
var totRectangles = myDoc.rectangles;

for(i=0; i<totRectangles.length; i++){
var myRectangle = totRectangles[i];
var myRectangleLevel = myRectangle.itemLayer.name; // the name of the Indesign's layer to which the rectangle belongs

var totGraphics = myRectangle.allGraphics;

for(k=0; k<totGraphics.length; k++){
  var myGraphic = totGraphics[k];

  if(myGraphic.imageTypeName == "Adobe PDF"){
   var myGraphicLayers = myGraphic.graphicLayerOptions.graphicLayers; // the layers of the Illustrator file

   for(j=0; j<myGraphicLayers.length; j++){
    var myGraphicLayer = myGraphicLayers.item(j).name; // the name of the current Illustrator's layer

    if(myRectangleLevel = "ES"){
     switch(myGraphicLayer){
      case "PT":
       myGraphicLayers.item(j).currentVisibility = false;
       break;
      case "ES":
       myGraphicLayers.item(j).currentVisibility = true;
       break;
      case "DE":
       myGraphicLayers.item(j).currentVisibility = false;
       break;
      case "FR":
       myGraphicLayers.item(j).currentVisibility = false;
       break;
      case "EN":
       myGraphicLayers.item(j).currentVisibility = false;
       break;
      case "IT":
       myGraphicLayers.item(j).currentVisibility = false;
       break;
      case "quote":
       myGraphicLayers.item(j).currentVisibility = true;
       break;
      case "Disegno":
       myGraphicLayers.item(j).currentVisibility = true;
       break;
     }
    }
   }
  }
}
}

I think the script is someway conceptually correct, but there has to be something wrong, as it doesn't work..

Any help would be much appreciated

Thanks in advance
