Calling functions from SOAP webservice. Can't access webservice functions.

Question

Hi flex gurus,
I am quite new to flex. I am working on an flex application where I am trying to remotely invoke a SOAP webservice which is a wsdl file from Adobe flex 4.6.
I have authenticated the webservice(Basic Authentication Done) and got access to wsdl but I am unable to call the functions in it. I just want to pass the username and password for the user login to the service function which will give me the data useful for my application, but nothing is returned when the webservice function is called.
I am totally blocked at this point. Please help me.
Thanks in advance.
