I found one thread that was related to this topic, but both of the 2 scripts don't function in a way that displays percentage change... The first script in the thread just displays zeros for me and the other displays value change not %. I was wondering if there was a way to code it in a way that would make it look just like %change and Mark%change built in columns, but displays the difference in percentage therefore showing aftermarket % change this way? I was just thinking maybe it could be simpler than people were making it out to be. Maybe not.
