<p class="MsoNormal">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:<o:p></o:p></p>

</span></span><![endif]>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.
