**VictoryBoosting**On my form, I have an option (let's call it "A") that will multiply an equation (B) by 1.25, when checked. By default the option to multiply B by A is unchecked, meaning it is uncalculated. However, if you were to check and then uncheck the A, A is now set to zero, instead of nothing. My form requires A to be in the calculation, as far as I know.

I am getting (0)equation

Instead of (nothing)equation**VictoryBoosting**I just realized the answer to my question is the number 1. I've had a long day.
