Correct Get URL syntax?

This is embarrassing–I’m not new to Flash but have just gotten an upgrade from MX to MX04 and the AS is killing me. I’ve got this code on a button—on(release) {
getURL(“”, “_blank”)

This is the error I get back-

Error Symbol=movie1, layer=links, frame=1:Line 1: Syntax error.
Button.onPress getURL(“”, “_blank”);

What is the correct syntax?
Also, what is the earliest player I can export to for max backward compatability?
