A preloader and publishing

A. <img src=http://www.ezboard.com/intl/aenglish/images/emoticons/ohwell.gif ALT=":">
I do not seem to be able to get the knack of how to do this.

In Frame 1 of the preloader which is in Scene 1

if Frame is Loaded (“Scene 2”, 16){
gotoAndPlay (“Scene 1”, 200)

In Frame 20 of preloader

gotoAndPlay (“Scene 1”,1)

It is being loaded from top down in publishing settings.
However it doesnt seem to be working as the whole movie runs normally but just slow


2.Also when publishing how do I stop the swf file being put on the left hand side of the page?
I usually do this manually in Dreamweaver but when i watch the flash on another computer it is aligned to the left?
