I created a simple .NET web service which selects data from a SQL server database and returns XML. Now I would like to bind a drop down component from flash mx professional to this webservice. Every time I try to add the web service to my flash project I get an error:

Flash was unable to find any Web Services from the following URL:
http://www.madisontitle.com/webservi...1.asmx/GetCats
what have i done wrong. if you go to that link it returns the xml that i need. do i need to do something to make the webservice public?

PLEASE HELP!
thanks.
