getURL For Action Script 3?

programming flash
1

I found out that the new isntruction is : flash.net.navigateToURL

but when I try to go to an URL:
[AS]
flash.net.navigateToURL(“http://www.mrsoluciones.com/quienessomos.html”, “_self”);
[/AS]

The compiler error window tells me:

“1067: Implicit coercion of a value of type String to an unrelated type flash.net:URLRequest.”

Any ideas what can I do to get to the URL with it opening in it “self”?

THANKS!
