Welcome to all newcomers!
Just a friendly reminder to all as per Rie's first post- please do not edit or input any info on the last 3 columns on the right (blue, pinkish, and yellow columns with the Lbs to Lose, Lbs Lost and % Weight Loss in the heading above each column respectively) since there are formulas in there. All you have to do is input your weight each week, that's it. It will auto-calculate what you have left to lose, etc for the last 3 columns on the right.
I've already went in and fixed it so no worries.
Have a great day, all!
