Trying to access XML data from for loop not working...

Hi,

This is driving me nuts!  I want to load images from an XML file into a scrollpane (which is also not working properly).  I am having trouble accessing my XML object--aVideos[index].imagei, where i is 1, 2, 3 etc.  If I hard code this to "aVideos[index].image1, aVideos[index].image2 etc" it works.  But, I would like to load many images from this XML object in a for loop.  Another expert suggest using "eval", but that didn't work or I didn't manage to use it correctly.  Can someone see what is wrong with my code?

Many thanks in advance!
for (i=1; i<=9; i++){ 
 
_root.mcMain.createEmptyMovieClip("imageholder+i", _root.mcMain.getNextHighestDepth());
_root.mcMain.imageholder+i.loadMovie(aVideos[index]."image"+i); 
setProperty("_root.mcMain.imageholder"+i, _x, i+390);
setProperty("_root.mcMain.imageholder"+i, _y, 0);
_root.myScrollpane.invalidate();
};

_root.mcMain.createEmptyMovieClip("imageholder"+i, _root.mcMain.getNextHighestDepth());
_root.mcMain["imageholder"+i].loadMovie(aVideos[index].["image"+i]); 
_root.mcMain["imageholder"+i]._x = i+390
_root.mcMain["imageholder"+i]._y = 0;

Hi,

This code unfortunately doesn't work as I get an error:

Expected a field name after '.' operator.

I don't understand why.  Plus, when I hard code the field--image1, image2, etc.  I can see the images, but there is no scrollbar or rather a blank scrollbar with no button to scroll.  It is like the scrollpane doesn't understand there are images in there.  Yet, if I set the "draggable" property to true in the scrollpane then I can drag the mc and see all of the images, so they are there but the scroll pane doesn't recognize it?

So, 2 problems--["image"+i]
And, even when image1 etc hardcoded, scrollpane not functioning.

Any help would be much appreciated!

Thanks!

So, this code is somewhat working--I had to change it to be loadMovie(aVideos[index]["image"+i] , so without the "."  However, I am still having difficulties.  This code is loading the 10 images.  But, the result is not correct.  

1) Image0 are starts x = 390, when the first one should be at 0 and the next 390.  If I hard code the set property x value to 0, it is as it should be.
2) I have no scroll button to scroll through, only blank scroll bar.
3) When I set "drag" to true, I can go through the images, but only see part of the last image....

So, something is wrong with my set up and I can't figure it out.

I thought this was supposed to be easy!!!!  I am very frustrated!
for (i=0; i<=9; i++){ 
_root.mcMain.createEmptyMovieClip("imageholder"+i, _root.mcMain.getNextHighestDepth());
setProperty("_root.mcMain.imageholder"+i, _x, i*300);
setProperty("_root.mcMain.imageholder"+i, _y, 0);
_root.mcMain["imageholder"+i].loadMovie(aVideos[index]["image"+i]); 
_root.myScrollpane.invalidate();
}
