Hi,

I have a project where I’m removing code for bandwidth detection, but after I remove it, my code in the }else{ won’t execute anymore like it did before. Not sure what I’m missing? Maybe a pair of curly braces somewhere? Here is before, and after bandwidth code removal:

---------- BEFORE (works): ----------

stop();

images\_xml = new XML();  
images\_xml.onLoad = startImageViewer;  
images\_xml.load(‘xml/flash.xml’);  
images\_xml.ignoreWhite = true;

// intialize variables  
function startImageViewer(success) {  
if (success == true) {  
rootNode = images\_xml.firstChild;  
// ‘totalImages’ is the variable name set to correspond with the the dynamic text instance of ‘totalImages’  
totalImages = rootNode.childNodes.length;  
// [totalImages = rootNode.childNodes.length;] gets the total number of childNodes (total number of image and text files) in your .xml document  
firstImageNode = rootNode.firstChild;  
lastImageNode = rootNode.lastChild;  
currentImageNode = firstImageNode;  
// ‘currentIndex’ is the variable name set to correspond with the dynamic text instance of ‘currentIndex’  
currentIndex = 1;  
// [currentIndex = 1;] sets the viewer to play the first childNode (first image and text file) in your .xml document  
updateImage(firstImageNode);  
}  
}

// Updates the current image with new image and text  
function updateImage(newImageNode) {  
// ‘imagePath’ is the variable name set to correspond with the .jpeg file name located in your .xml document  
headline1 = rootNode.childNodes[0].attributes.headline1;  
headline2 = rootNode.childNodes[0].attributes.headline2;

```
headline3 = rootNode.childNodes[1].attributes.headline1;
headline4 = rootNode.childNodes[1].attributes.headline2;

headline5 = rootNode.childNodes[2].attributes.headline1;
headline6 = rootNode.childNodes[2].attributes.headline2;

headline7 = rootNode.childNodes[3].attributes.headline1;
headline8 = rootNode.childNodes[3].attributes.headline2;

headline9 = rootNode.childNodes[4].attributes.headline1;
headline10 = rootNode.childNodes[4].attributes.headline2;

image1 = rootNode.childNodes[0].attributes.image1;
image2 = rootNode.childNodes[1].attributes.image2;
image3 = rootNode.childNodes[2].attributes.image3;
image4 = rootNode.childNodes[3].attributes.image4;
image5 = rootNode.childNodes[4].attributes.image5;

```

}

// Bandwidth Detector  
/\*  
Downloads a hidden test image from a predefined URL  
and determines client bandwidth based on how  
quickly the image is downloaded. Test image must  
be ~12k in filesize (smaller filesizes result in inaccurate  
detections on fast connections). Image is not cached due  
to random string added to URL.

“Test” variable in calc\_bandwidth(); is bandwidth value.  
(~300kbps cable/DSL, ~20kbps dialup)

The text field on the stage can be safely removed.
