title: Masking answer options in Confirmit (jscript)
body: <p>I'm trying to mask the answer options that show up in a 3DGrid question item in Confirmit, using the value of a background variable.</p>
  
  <p>E.g. when "background1" ==1, display answer category 1.  If "background1" ==0, do not display answer category 1.  If "background2" ==1, display category 3, otherwise do not.  In any case, display answer category 2.</p>
  
  <p>Hopefully this is easy for someone out there (I'm a psychologist, not a coder...so not so much so for me :/)</p>
  
  <p>Thanks!</p>
