For some text-box or essay questions I want to display an additional text “What other respondents have said:”. Here, some randomly selected entries from other responses shall be listed.
In ideal case, I can access by custom scripting an object where all answers to the textbox (i.e. answers from all responses) are stored. Then I could evaluate the content using PHP.
So, my question: can I read out by custom scripting all previous answers to a textbox / essay?
