Hi all,
I'm newbie to javascript. I want to write a script, where i'm calling a function which is in another javascript(Ajavascript).

function B()
{
var ins=Ajavascript.listInstances();
document.write(ins);
}

B();

i coudnt view the output @ the browser. Is this approach wrong? how can i correct it?
Any assistance will be really helpful to me.
thanks.
