[Problem with Horizontal scroll magic with accordion]

I have some problems with scroll magic goes horizontal example. I have part of my portfolio website which I have some accordion images and I want them to expand to their 100% width as the people scroll the page. not by hovering. 
like what norgram.co is doing more or less but I just want it on my images.
so I started to use the go horizontal structure of the magic Scroll and nothing is working and I don't know why.
