This question comes from one of our Psychology professors . So here's what I am trying to do with the short answer . . . I want students to enter a numeric value between 1 and 400 and any of the values would be "correct".
 

I have entered the 400 values into the answer. I have tried using spaces between consecutive values as well as commas, but regardless any numeric answer is graded as incorrect. How does one enter numeric answer values so that the system recognizes a numeric response? I don't want to type in the names of the 400 values, not only because of the work, but also students would need to precisely type in something like "two hundred and twenty-two" or "three hundred and fifty-eight". I'm not confident students could do that.
