Very hard to answer as you are not very precice with your question, no code and there is no dropdown menu on that link (your sever is working fine).
Very simple create a movie clip with button inside. These buttons are able open areas in your flash movie as well as other movies or url. The action should look something like this:
on (release) {_root.gotoAndPlay(181);}
This might help:
