Add restriction for selecting two contradictory response options in kobotoolbox

[Kal_Lam]

Hi @Javed.Mazher,

Welcome to the community! Please see the discussion that has happened earlier which should solve your issue:

How to set a constraint (validation) while selecting a response from a Multiple Choice Question

Within Multiple choice questions is there a way we can put a validation where, for the options of none-of-the -above, the other answers get erased or are not entered?

Have a great day!
