my edge animation is disappearing from my website

Hi, I've been puzzeling for days now.

I've made a picture slideshow in edge. and it's on my home page.

my page is build in different div and my home.php is loaded in one ofthe div. this works great, but if i load an other page in the div and then go back, then my animation is not there anymore

see this image when page opens for the 1st time

this happens if i use the menu to go to other page and then go back to home

Any idea's

Thanks
