Well, my experiment involves a prioritization of 12 custom items to respond to, and through a very large responses.xls file and relisting the items in the questionnaire 12 times, I have gotten it so that they rank order the 12 items and then must go through the list in that order. If I were to change the names of the variables so as not to get the message, I'm not sure I would be able to juggle everything correctly in the responses.xls file.
