Merge Item descriptions in to one item

Question

I have item descriptions from three different items. I would like to merge them into one item.

Here is my pipe link,

I currently have output in items 0,1,2. I want the item description from 1 and 2 to be added into 0. Can someone give me some ideas how to do this ?

Thanks in advance.
