I have a question (it’s textbox list) where the respondent must indicate the maximum and minimum price of the product in different fields. can I prevent the respondent to write in the “lowest price” field number greater than the value that he pointed to the “maximum price” field?
There is no built-in validation function within SurveyGizmo that would allow this type of response comparison to occur within a text box list. The simplest way to handle this might be to create two separate text box questions. You could set up a TEXT/MEDIA element containing an error message beneath the second question and use logic to trigger its appearance (only show this element if Q1 > Q2) if the ‘lowest price’ response is greater then the ‘highest price’ response.
