Button triggered popups

Question: Being new (and green) to Flash I am obviously in dire straits looking for a solution to the following problem which might be fairly easy for an advanced Flasher to solve:
I need to make an interactive map of a country with information popup windows. Here is what I mean: the country is divided into 16 regions: when a user scrolls over a region it changes its look (this I can do), when a user clicks on a region a text window appears with information about the region–this information should include links to additional pages and this text window should stay visible only when the user decides to use it and disapear when the user moves onto another region. If you know of a toturial about it or an example I can examine I’d really appreciate it. Can anyone help? Thanks.
