Dynamic Menu Spacer

How do I put a spacer of 50 pixels in between each category of this dynamic menu system and not have it put an additional 50 pixel spacer at the bottom?  This 50 pixel spacer should only insert if the there are two or more categories.  

Here's the link:  http://dev.fusionapps.com/wboe/flash/right_nav/flashmenu.html

Here's the code:

data_var = new LoadVars();
data_var.path = this;
data_var.onLoad = function(ok)
{
     if(ok){
          this.path.menuGeneration(this);
     } else {
          trace("CFM PAGE MISSING");    
     }
};

function menuGeneration()
{
     var startY = 1, depth = 0;
     var temp = data_var.cats.split("|");
      
                     //new TextFormat([font, [size, [color, [bold, [italic, [underline, [url, [target, [align, [leftMargin, [rightMargin, [indent, [leading]]]]]]]]]]]]])
     var style1_fmt = new TextFormat("textFont", "14", "0x000000", "bold", "false", "false", "", "", "center");
     var style2_fmt = new TextFormat("Verdana", "12", "0x000000", "true", "false", "false", "", "", "left", "3", "5", "");
     for(var i = 0; i < temp.length; i++){
          var mc = this.createEmptyMovieClip("main" + depth, depth);
          depth++;
          mc.lineStyle(1, 0x912211, 100);
          mc.beginFill(0xEDD593, 100);
          mc.lineTo(198, 0);     mc.lineTo(198, 20);     mc.lineTo(0, 20);     mc.lineTo(0, 0);
          mc.endFill();

          mc.text_txt.selectable = false;
          mc.text_txt.embedFonts = true;
          mc.text_txt.text = temp[i];
          mc.text_txt.setTextFormat(style1_fmt);
          mc._x = 1;     mc._y = startY;
          startY += mc._height + 4;
          var subText = data_var["subcats" + i].split("|");
          var subLink = data_var["urls" + i].split("|");
          for(var j = 0; j < subText.length; j++){
               var sc = this.createEmptyMovieClip("sub" + depth, depth);

               sc.text_txt.setTextFormat(style2_fmt);
               var hgt = sc.text_txt._height + 2 > 20 ? sc.text_txt._height + 2 : 20;
               sc.lineStyle(1, 0x912211, 100);

               lc.beginFill(0xEDD593, 100);
               lc.lineTo(197, 0);     lc.lineTo(197, hgt - 1);     lc.lineTo(0, hgt - 1);     lc.lineTo(0, 0);

               lc.link = subLink[j];

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.
