I want to use a checkbox to control the visibility of an intermediate result. In the past I've used conditional formatting but I don't think it's possible this time. I still want the numbers to be present in the given cells - I just want to be able to control whether the user can see them and to be able to use a control such as the checkbox to reveal the intermediate result or to keep it hidden. Ideally, I'd also like to be able to avoid a recalculate if at all possible. Any suggestions?

TIA
