app.beginUndoGroup("Set opacity mask");

for(var j=0;j<app.project.activeItem.selectedLayers.length;j++){
var myLayer = app.project.activeItem.selectedLayers[j];
var myPath = myLayer.property("Masks");
var numMasks = myPath.numProperties;
for(var i=1;i<numMasks+1;i++){
if(myPath.property(i).name.replace(/Mask /g, "")==myLayer.index) myPath.property(i).maskOpacity.setValue(100);
else{
myPath.property(i).remove();
numMasks = numMasks-1;
i--;
}
}
}

app.endUndoGroup();
