There is that "iterative" setting. In Excel (Windows), go to File/Options/Formulas and enable Iterative Calculation.
Otherwise maybe download a fresh copy?
Right. But if your problem is not having enabled iterative calculations, you'll already have gotten a dialog box and arrows all over the place letting you know that's the problem.
Values Recovered.
Went to Water Profile Adjustment page.
The box under Acids, Mash was blank. I selected Lactic and all my values were restored.
Thanks for your suggestions
