Customised forced response for side by side question

This seems like something you could accomplish with Custom Validation. If you are new to this feature, it can seem complicated at first, so you’ll want to build each condition one-by-one and test it before adding the next condition. And make sure not to use Force Response when you’re using Custom Validation.

I have set up the custom validation like this: 

This allows survey takers to enter one program preference with one intake and pass validation, but also enter two program preferences with one intake, and still pass validation. This should not pass validation, though, only when an intake for program preference 2 is selected should validation pass. 

Is there something wrong with my logic?

I think you’ll need to spell out the exact conditions for all permitted scenarios of lines 2-5 in each logic set (the conditions found between each bold “OR”) after the first.

It would be something like this; the first two conditions in your logic are correct as is.

Preference1 is not empty

and Intake1 is not empty

Preference2 is empty
