packages cannot be nested???
HI, I am trying to compile my QR Code reader App using Adobe flash CS6, but keep getting the error "packages cannot be nested"
My code is as follows:
package
{
import com.logosware.event.QRdecoderEvent;
import com.logosware.event.QRreaderEvent;
import com.logosware.utils.QRcode.QRdecode;
import com.logosware.utils.QRcode.GetQRimage;
import net.hires.debug.Stats;
import com.bit101.components.*;
import flash.media.Sound;
import flash.display.*;
import flash.media.Camera;
import flash.media.Video;
import flash.events.*;
import flash.utils.Timer;
import flash.desktop.NativeApplication;
import flash.geom.Rectangle;

NativeApplication.nativeApplication.exit();
}
}
}
IS THERE ANY ONE THAT CAN HELP, AS I AM NOT SURE WHERE I HAVE GONE WRONG!?!?
Thanks
