Groups of questions can quickly and conveniently rotated using the Rotational Groups feature. For example, your survey covers five types of sandwiches, asking the same questions for each. Program the first set of questions, and then copy this question set four additional times. Modify the text as needed. Then, group each set of questions. Your Survey Editor will resemble the question layout in the right thumbnail.
Once you have your question sets finished, select Survey Functions > Rotational Groups from the Survey menu, or select the cicular arrow icon at the top right of Survey Editor.
This will bring you to the following screen, which will display all of the groups that you have programmed. Indicate which groups you wish to rotate or fix as shown below and click 'Activate this Group.' This will rotate your groups as you specified on the prior page.
