Applying external AS

I’m working on my first flash website and following this tutorial: link (it starts on the page I’m having problems on). I downloaded the AS that the author recommends and unzipped it into the file that contains my flash site as well, however I get “1093: Syntax error.” from "#include “”, as well as a few other areas, whenever I go to publish it. Since this is my first site, I’m not sure where to look for the problem, so if you need any more information I’ll be very happy to provide it. I do believe, however, that the problem has something to do with either the actionscript in Flash being incompatible with the AS provided or I didn’t install the AS right. I can provide the .fla if needed.
