getUrl does not send current dynamic variable

[roddyguy]

I needed to create a flash scrollbar with dynamically generated
thumbnails that would link to a page and send the ImageID as a URL
parameter. Could not find much reference material for this, was but
successfully able to produce such a scenario... almost. My problem is,
that even though my ProblemVariable (taken from a Dataset) displays
correct ImageIDs and Thumbnails (loader objects) display correct
Thumbnails (within a while statement)...The ProblemVariable when placed
in the repeating getUrl function always links to the last
ProblemVariable set and not the current.

The only reason I had added the Label object was so that I could test
that the problem really was within the getUrl function. Sure enough,
the Label's HTML link with the ProblemVariable works perfectly because
it is picking up the current dataset record.

I'm sure the reason that the repeating getUrl functions keep grabbing
the last ProblemVariable set is because the function actually happens
outside of the loop and because the variable is not static, it will
always grab the last value set.... but does anyone know and answer to
my problem. I have been wresting with this for days now. I have tried
using 'eval', 'String.concat', 'loadVars.send', among other things.

I'm sure there is a simple answer, but it is out of my expertise.

Below is my code for the movieclip that resides in the scrollpane:

var thisim:Number = _root.iid;
var numstr:Number = 0;
var ImageDepth:Number = 0;
var LabelDepth:Number = 10;
var yVal:Number = 10;
var strImageName = "loader"+(numstr);
var strLabelName = "label"+(numstr);
var ProblemVariable = "";

while (images_dataset.hasNext()) {
if (images_dataset.currentItem.ImageID != thisim) {
newxImage = createClassObject(mx.controls.Loader, strImageName,
ImageDepth);
newxImage._y = yVal;
newxImage._x = 10;
newxImage.contentPath = (images_dataset.currentItem.Thumbnail);

newxLabel = createClassObject(mx.controls.Label, strLabelName,
LabelDepth);
newxLabel._x = 1;
newxLabel._y = yVal;
newxLabel.html = true;

ProblemVariable = images_dataset.currentItem.ImageID;

newxLabel.text = "<a
href=\"project_category.php?iid="+ProblemVariable+ "\">"+ProblemVariable+"</a>";

newxImage.onPress = function() {
getUrl("project_category.php?iid="+ProblemVariable +");
};

yVal = yVal+110;
ImageDepth = ImageDepth+1;
LabelDepth = LabelDepth+1;
numstr = numstr+1;
strImageName = "loader"+(numstr);
strImageName = "label"+(numstr);
}
images_dataset.next();
}
stop();

someone on another board gave me the solution. I hope this helps
others:

newxImage.ProblemVariable = images_dataset.currentItem.ImageID;
....
newxImage.onPress = function() {
getUrl("project_category.php?iid="+this.ProblemVar iable+"");
};

This solves the problem ... a local variable in the newximage object,
wich will have no connection with the changes in while {
