Accepting Blank data entry fields
We have a slide containing multiple data entry fields for text entry answers for multiple questions on the same slide. Each data entry field is referenced to a separate individual quiz short answer slide, so that we can run the quiz slides in the background at the end of the section and submit the answers together. We did this to get around having more than one question per page.
It works great except when someone does not enter any value in a particular data entry field, then it stops during submission at the respective quiz slide for the blank field and pops up the invalid answer box. At that point the whole thing stops because there is no way to go back and enter an answer on the original slide, nor do we want that to happen.
What we want is for a blank entry field to be accepted as an answer, so we just get a report showing they didn't answer that question.
How do we do that?
