I am trying to create a field in the data load editor that is based on a condition of other loaded fields. the data base is about chess, my goal is to find the gap in ratings for each game ive loaded. i am wanting to write a condition as follows
if black is winner than (black_rating - white_rating), if white is winner than (white_rating - black_rating)
fyi: existing relevent fields
winner (possible values are black, white)
White_rating (eg. 1400)
Black_rating (eg. 1600)
