I am coming here to express my frustration. It has been quite a while since I have ventured into Pipelines. I just spent 15 minutes adding all the fields one at a time to the search step and none of them show up in the loop step. I don't want to loose any changes so I am opening all the steps and hoping that moving things around will finally add the fields I selected in the first step so I can pick them in the loop step. Doing this for a while, no fields appearing, I give up and refresh the page. EVERYTHING IS GONE!! Now I start over.
Going back to cave.
