Hi,
In between there are five more answers, which the survey participants can arrange accordingly.
My first thought was: "Why do you offer these two options in the ranking question?"
To preset the first rank is rather easy by setting the relevant code to this first rank in a question of type "equation"
but a bit useless as the respondent may rearrange.
So I'd prefer a validation
But you did not tell us how these two items are selected. Are the constant? Probably they depend on some previous answers?
So to create a working validation equation you should tell us.
