Requiring response for free format questions

Question

I know that you can require a response for any of the variables in the free-format question, but what I am trying to do is require that the participant provide input for one of the options without forcing them to choose which option they respond to. In other words, I need for them to do one, but it doesn't matter which one. Is there a way to do this?

Comments

Sure.  What variable type are you using (e.g., checkboxes, textareas)?  What are the names of these variables?

Answer 1

To enforce responses across multiple variables in a free format question you can use Custom JavaScript Verification. You can find some examples in this help article on Custom JavaScript Verification: http://www.sawtoothsoftware.com/help/lighthouse-studio/manual/hid_web_advanced_javascript.html#customjavascriptverification.
