NSAppleScript Returned Value
===

How do I get the returned value from an NSAppleScript.
I am using apple script to get the song title in iTunes and take that value and set NSMenuItem's title.

My code: .M

    //run applescript
    NSAppleScript *script = [[NSAppleScript alloc] initWithSource:@"tell application      \"iTunes\" to set song to name of current track"];
    [script executeAndReturnError:nil];
    //set menu item title
    [songName setTitle:script];

My code: .H

    IBOutlet NSMenuItem *songName;
