Hey, guys newbie here so please go easy! We are starting a biggest loser weight loss deal here at work and I was wanting to put it on a spreadsheet. Probably a pretty easy deal, but I don't know the formula to use. this is what I want:
Joes start weight 200 minus week ones weight, then the original 200 minus week 2's weight and so on till week 8.
I want to keep a running total of weight lost in pounds as well as percentage.
Any help would be great!!
