I am trying to set a validation setting to display an error message. I have a column Type set to choice (Radio buttons) with two options (No Time and Minutes), I have a further column MinutesSet set to number.
What I need is that if Minutes is selected from the Type choice the column MinutesSet must contain a number.
I would also like that if No Time is selected from the Type choice and the user enters a number in the MinutesSet column it will display error.
What would the formula be and should I just use the Validation in the Minutes column as this is available or should I use the Validation option in the generic settings?
