Random Image Generator?

Hey guys, so before I decided to post this. I read on the forums a lot, and tried to follow the tutorials but I keep getting tons of errors whenever I start. The latest forum I got on was this: http://www.ozzu.com/flash-forum/random-image-generator-works-great-t23311.html

I tried to follow what everyone said there, but I still had a lot of errors. I'm sure I'm doing something wrong.

Pretty much what I want to achieve with my file is that every time the browser is refreshed, it goes between 1-5 ads.

Here is the file: http://www.media****.***/?tmolzdttzod

P.S. I can't post links for some reason, and my file is 1.1 megabytes
so the ****.*** = fire.c0m

Guys, thank you so much!
