Two Constraints in One Question

[wiydiy]

Can you put two constrain in one question?

It is a multiple select type question, the maximum choice is 3 and the ‘none’ option cannot be selected with other choices.

Can i put both constraints in one question?

Thank you.

Yes, you can use the constraint.

count-selected( . ) < 4 and ((. = ‘98’) or not(selected(.,‘98’))) use this constraint, where 98 is code of none, you can use your own code as well.
