Construct dynamic menu through iteration of [for each]...

Question

Hi,
I'm trying to create a menu based off a json file structure. Per the code below, I'm trying to build a menu structure that resembles the image below. In order to complete this piece of code, I'm trying to figure out what [mcMenuItem.y] and [mcLessonItem.y] would be. I know this is a seemingly simple problem, but I haven't done something such as this in some time and it's slipped my mind on how to construct the y value through iteration. Any help would be very appreciated,

for each (var module:Object in courseData[0].modules)
    var mcMenuItem:mcMenu=new mcMenu();                           
    menuHolder.addChild(mcMenuItem);                                       
    mcMenuItem.name = "mcMenuItem" + i;
    mcMenuItem.y = mcMenuItem.y + (mcMenuItem.height * i);
    for each (var moduleNumber:Object in module)
        j = 0;
        for each (var lessons:Object in moduleNumber)
            var mcLessonItem:mcMenu=new mcMenu();                           
            menuHolder.addChild(mcLessonItem);                                       
            mcLessonItem.x = mcMenuItem.x + 25;// + mcMenuItem.width;
            mcLessonItem.y = (?);
            mcLessonItem.name = "mcLessonMenuItem" + j;

You'll need to have a yValue variable that you increment as you add each new menu item.  The increment value will be the height property of the item last planted.
