Dynamic Panel On Scroll

Hi folks. New here and to Axure.

I’d like to do something when I’m scrolling down the page but specifically when I reach and am still scrolling in a particular panel. Specifically I’d like to cycle through 3 images as I scroll and then reverse on the way up. But only in this panel.

I can use Mouse Enter to fire once but that’s not really what I want.

Tried to use the Scrolled Down (or scroll anywhere) event in a dynamic panel but that doesn’t seem to register. I’m not finding docs to be very specific in describing exactly what events are and when they fire.

Am I not understanding what Scrolled Down is or how to do this? I mean clearly I don’t know how to do it.

Thanks!
