If you notice at the end of the code... gotoAndPlay.. that brings it to frame 6 in the movie.. at about the 15th frame I have an action in that frame to get url http://partypelican.ning.com . Say you have it gotoAndPlay frame 6 and on 7 you have it get url... when it loads your page.. it won't show your logged in ( but you will be logged in and it will show once u click another page).. so you need to give it some space in between. 15-20 is good. play around with it.
