Delete child created in another function

This is my first venture into the world of classes so apologies in advance for my newbie terminology. I have implemented a very nice “Busy” indicator courtesy of Daniels Tech Ramblings and it’s initiated by:

var loadInd = new LoadIndicator(this, 250, 200);

and is stopped via:

loadInd.destroy();

My problem is that the variable ‘loadind’ is created in one function and I need to stop it in another function where said variable is unknown - Variable loadind is not defined.

How do I get around this?
