I have a survey that has say 3 questions : Q1, Q2 and Q3. Suppose that a respondent get only Q3 and when I ask Q3 I need to know if Q2 was unanswered.
If I write in the logic: Q2 = "" this is wrong and Q2 = 0 is not right . How can I know if this question is unanswered ? What is the value connected to an answered question ?
Please note I have also run a javascript alert and I made sure that the value is not null, "" or void(0).
Do you have any clue ?
Many thanks.
Luigi
