I used this
but it did not work on the website!
I need the animation on my website to run when it is visible, and continue running when out (top or bottom), and only run once. Thank you.
and again: without any url or/and hypefile the only advice can be to pray
One thing to note is that if you have your Hype document in an iframe it will not work as expected -- you'll need to have your Hype document embedded as a regular DIV.
