ActionScript 3.0 :: New URLRequest Not Working

I cannot ascertain why the code for one set of navigation buttons I've created works, but similar code does not. The code is rather lengthy, but I've pulled out the salient components to see if the Interwebs could help.

Here's the script that IS working:

Listener code:

Code:
cswordbutton.addEventListener(MouseEvent.CLICK,fetchcswordassets);
And the function code that goes with it:

Code:
function fetchcswordassets(e:MouseEvent):void{
var url:String = "knowntomeURL";

[Code].....

1) All of the actions are in a separate layer in the first frame;

2) There is only one scene;

3) I've given the same button a different instance name in many cases, to coincide with different expectations (URLs).
