Bypass extension if already initialized? HELP!

I am working on an app using AIR for Android and I have come to a bit of an issue during final stages of debugging.

I have a total of 2 frames being used and on frame 1, I have an extension initialized. I have a button that takes the user to frame 2. On frame 2, there is a button to return to frame 1. Every time I return to frame 1 I get an error message saying that the extension has already been initialized.

I have attempted, using my limited knowledge, to form a simple if-then statement to bypass the initialization if already initialized but it isn't working. Here is the code I used:

var EXTENSIONActive:Boolean=false

if(EXTENSIONActive==false)

{

  EXTENSION.init("");

  EXTENSIONActive=true;

}

Any insight would be useful, preferably the full code along with explanation as to why my code didn't work. (I want to learn from this experience)

Thanks for the help!
