I am trying to do something with a customresponse part that I cannot do really cleanly with normal response types, but am having some trouble evaluating the inputs. The inputs include numeric and text values as part of a single array input. I am having to problems:
1. I have not been able to figure out a way, in the "if" statements, to distinguish between a zero (0) answer and a null ("") answer.
2. The string components evaluate to true for any text value. Only numeric entries evaluate as false.
1. Is there a way to distinguish between a 0 and a null (i.e., no) response?
2. Is it possible to input both numeric and string values in separate textline inputs within one customresponse section?
