hi,
I am developing a windows app and I finished 75% of work in it .
In the app a section contains two div elements scrolling vertically. when I scroll the divs it should match with the element in the other div and produce a result.
I tried to make scrolling div elements to match but failed..
I put a screenshot of my app and you will understand it 
In the above screen first green box is one scrolling div and the other red one is one another. At the center comes near "+" the elements in div match and produce a result in the next rose box
Please guide me to finish the app by providing a solution to match the elements in different div
