map.removeLayer(myLyr) does not work

Question

Scenario description:
Created several checkboxes.  If a checkbox is checked, a layer is added, or else, the layer will be removed (see the code below).  However, I can't remove the added layer(s).  I run debugging, it does go through map.removeLayer(lyr), but the layer I created is still on the map.  If you have a better approach or find anything wrong in my code, please help.  Thanks.

private function ChkSettings (chk:ImageCheckBox, lyr:GraphicsLayer, 
    ac:ArrayCollection, lyrName:String ):void {
   if (chk.selected == false) {
 lyr.clear();
 for (var i:Number = 0; i < map.layers.length; i++) {
  if (map.layers.name == lyrName) {
   map.removeLayer(lyr);
  }
 }
   } else {
 lyr = AddGeocodeLayer2(ac);
 lyr.name = lyrName;
 map.addLayer(lyr);
   }
}

Problem solved,

if (this.map.getLayer (layerID)) this.map.removeLayer (this.map.getLayer (layerID));

where layerID is the given layer.id when the layer is created, e.g., could be the same as lyr.name in your case.

Hi - I'm having issues with this too - I've tried

map.removeLayer(map.layers[0]);

(The layer I want to remove is index 0)

This results in[

CODE]
* ncaught TypeError: Cannot read property '0' of undefined basecode.js:981
* switchBaseMapbasecode.js:981
* onClick
* _d66._onClickinit.js:34
* _2cfinit.js:15
* _b24._onClickinit.js:34
* (anonymous function)init.js:15
* _7bbinit.js:34

map.removeLayer('mainmap');

The gives no errors, but doesn't do anything, the layer is still showing if I Look at console.debug(map)

Cheers
