Shadowbox, lightbox, javascript, help PLEASE

i am in dire need of help. i have been all around testing lightbox, videobox, mediabox, and now shadowbox.

NO WHERE does it say how to implement shadowbox into flash. i have a button in my flash movie that when clicked, i would like it to be able to use shadowbox and open a flv or image.

i need help creating the javascript for the button and the html holding my main swf movie.

i have seriously tried every means and have no clue where to go from here. i would appreciate it ANY help fore this is driving me nuts.

thank you,
mike
