Making a form field conditionally required
Good morning Hive Mind!
We have a form where our SalesOps group wants two fields:
* Phone
They want to set it up so that one or the other is required, but AT LEAST one must be filled out. That is, if someone fills out Email, they don't have to fill out Phone and vice versa, but ONE of the two fields must have a value. How would we do that?
