can someone help me? I need a script code for Photoshop cs 6, that mirror all the layers in a group, not the group, every layer individual, please!

               ref.putIndex( charIDToTypeID( 'Lyr ' ), i );

               var desc = executeActionGet(ref);

               var layerName = desc.getString(charIDToTypeID( 'Nm  ' ));

               var ls = desc.getEnumerationValue(stringIDToTypeID("layerSection"));

               ls = typeIDToStringID(ls);

               if(ls == "layerSectionStart"){ x++};

               if(layerName.match(/^<\/Layer group/) )

               {

                 y ++;

                 r = x - y;

                 if(r == 0 && ls == "layerSectionEnd"){break};

                 continue;

               };

               if(ls == "layerSectionContent"){mirrorByIndex( i, pivotPos, mirrorDirection )};

          };

     }

     multiSelectByIDx(idx);

}
