Can't open projector

Hi all, I have a projector that I'm using as a menu, when I click buttons on the projector I want to open other projectors and close this menu projector. What is the best way to accomplish this? I tried the following statements before but they only worked while playing the menu movie in director itself not when a projector was created:
code:
onmouseUp
go to movie the moviePath & "MovieToOpen"
end
I also tried:
onmouseUp
go frame ("Start") of movie ("MovieToOpen")
end

Thanks in advance. Any help will be appreciated.
