Voet's transition tutorial problem

i have my main swf that everything loads into. then there are a bunch of other swf’s that load into it. most of them work but there is one that when you click on the button it reloads the main swf. then when you click on it again it works. i have been kicking myself in the *** for 2 days with this. why won’t it work?

EDIT: i forgot to mention that everything works fine on my computer. the problem only occurs when i upload the site. i am also using the same exact movie except for the content. sigh i am frustrated.
