Navigating to my as file

I am creating a website in flash with project swfs embedded and my file directories look like…

main.swf
projects_dir
…setup.as
…project1_dir
…project1.swf
…project2_dir
…project2.swf

my question is how do direct the import statement in the project swfs up a directory to the setup.as file?

I tried ‘…/’ but it didnt like that.
