Issue swapping coordinates of PNG stored in 2D Array

Question

Hi,
I'm using the interactive png class found
here
I'm loading in the the required date from an xml file which
is structured like this
<?xml version="1.0"?>
<theData>
<_title_>pictures!</_title_>
<_url_>images/</_url_>
<slides>
<sub image="images.png" region="region1" info="region 1
info - links to bbc" _url="
http://www.bbc.co.uk" xLoc="0"
yLoc="0" image2="images2.png"/>
</slides>
</theData>
the images are loaded into a loader and stored as
interactivePNG. I give them an x,y coord but on rollover i need
them to swap coordinates. I put the interactivePNG in the next
available space in the regionArray which is stored in the mapArray.
So i need to swap the currentTargets interactive png x and y
coordinate with the interactive png x and y coordinate that is in
the same regionArray but one position later. i.e if the first one
is mapArray[0][8] i need it to swap x and y with mapArray[0][8]
How can i get them to swap, i just cant get it done...... If
tried using indexOf the currentTarget in the mapArray but it
returns -1.....
please help, thanks in advance

So try adding an 'index' property to the instance that is
equal to nCount01 for that iteration. In addition, you can add a
property that holds the value of the second dimension where you're
storing the instance, like 7 or 8...
thePNG.x = mapArray[nCount01][4];
thePNG.y = mapArray[nCount01][5];
thePNG.name = "1";
thePNG.alpha = 1;
thePNG.visible = true;
thePNG.index = nCount01;
thePNG.storedIndex = 7;
Then in your rollOver and rollOut handlers you could do
something like this:
var idx:int = evt.currentTarget.index;
var storedIndex:int = evt.currentTarget.storedIndex;
if (evt.currentTarget.name = "1") {
evt.currentTarget.x = mapArray[idx][storedIndex + 1].x;
evt.currentTarget.y = mapArray[idx][storedIndex + 1].y;
