[flexcoders] Access of undefined property of type URLLoader

[anuj181]

Hi 
I am simply trying to load external XML file but the builder is not
recognizing one of my variable named urlLoader of type URLLoader. it
is saying "Access of undefined property urlLoader, urlRequest and
completeListener. Does anyone has any idea what's going on.

Thanks
