Can't stop scroller! Please help! So I can have a drink! ;op

1

Ok, so I have a scroller, with buttons on eachside, when the buttons clicked it slides either way on the x direction to show another images (holder). Right now it just jumps from image to image, and I’ll put easing on it once I get this figured out. BUT, I can’t get it to stop at the constraints of my dynamic movie. Right now I have 10 images in and I can trace all the maxWidth etc, but my first one always comes up NaN, so I can’t find the beggining. Below is my code as well as some of the traces I have done to try to get this to work.

Traces:
totalClips I get 1,2,3,4,5,6,7,8,9,10 (I just want the last one tho, how do I get that?
w_clips I get Nan, 161.5 (9times sorry, not gonna type 161.5 and confuse ya)
**totalWidth **I get NaN, 323, 484.5, 646, 807.5, 969, 1130.5, 1292, 1453.5, 1615
maxleft I get 10 undefieneds.
and maxright, I get NaN then the distances. How do I set this up so I don’t get the NaNs and undefineds, and how do I stop my movie from moving on my left and right btns when it reaches these max widths??

function loadXML(loaded) { 
if (loaded) { 
  xmlNode = this.firstChild; 
  image = []; 
  description = []; 
  title = []; 
  link = []; 
  btn = []; 
  total = xmlNode.childNodes.length; 
  var xPos = 90; 
  for (i=0; i<total; i++) { 
   image* = xmlNode.childNodes*.childNodes[0].firstChild.nodeValue; 
   description* = xmlNode.childNodes*.childNodes[1].firstChild.nodeValue; 
   title* = xmlNode.childNodes*.childNodes[2].firstChild.nodeValue; 
   link* = xmlNode.childNodes*.childNodes[3].firstChild.nodeValue; 
   btn* = xmlNode.childNodes*.firstChild.nodeValue; 

   var scrollerMovie = attachMovie("scrollerMovie", "new"+i, i, {_x:xPos, _y:42}); 
   xPos  += scrollerMovie._width+20; 
   scrollerMovie.picture.loadMovie (image*, 1); 
   scrollerMovie.desc_txt.text = description*; 
   scrollerMovie.title_txt.text = title*; 
        var totalClips = scrollerMovie=i+1; 
        var clipBaseName     = 'new'; 
        var w_clips         = _root[clipBaseName + '1']._width+2; 
        var totalWidth         = (totalClips * w_clips); 
        var maxleft         = ["new"+i]._x; 
        var maxright         = (totalWidth/2); 
        trace(maxleft); 
   } 
   
} else { 
  content = "file not loaded!"; 
} 
} 
xmlData = new XML(); 
xmlData.ignoreWhite = true; 
xmlData.onLoad = loadXML; 
xmlData.load("images.xml"); 

_root.leftBtn.swapDepths(99); 
_root.rightBtn.swapDepths(109); 
_root.lines.swapDepths(89); 


         
leftBtn.onRelease = function(){ 
     for (var i=0; i<total; i++) { 
    _root["new"+i]._x += 161.5; 

    if(_root["new"+i]._x <= maxleft){_root["new"+i]._x += totalWidth;} 
     
     } 
    } 

  rightBtn.onRelease = function(){ 
      for (var i=0; i<total; i++){ 
      _root["new"+i]._x -= 161.5; 
     
      if(_root["new"+i]._x >= maxright){_root["new"+i]._x -= totalWidth;} 
     
      } 
     }
