Dropdown field - fail validaion on choice of one options

divixpl 03 May, 2019
Hiya! Really simple thing that got me very confused. I have a dropdown field with options y=yes and n=no. Now, if a user chooses no I need the field to fail validation making the form unable to submit. I believe I need to specify that condition in the 'Validation rules' box but I am clueless as to what to put in there. Is there something I am missing? Thank you!

Hi divixpl,

Why would you have a No option that is not valid? It does nothing but confuse the user.

The 'usual' way to do this is with a check box that is required.

EASY. Just do
And set it to required. This way No has no value, and validation will fail.

Thank you very much for help! That's exactly what I needed. I do realise it may seem confusing, I needed a drop down list where only one option would be invalid, above helped me just fine.
