Hi--
I'm trying to add a back button for an experiment (NOT a survey page) in order to go back to a previous trial. I generally know how to use conditional logic -- the only problem is that the trials are randomized, so it's not entirely clear which trial to display. The relevant part of the experiment is set up as follows:
3 randomized trials:
<block similar>
/trials = [1-3 = noreplace(6_by_2, 10_by_2, 12_by_2)]
</block>
I'd like to add conditional branching to each of these trials (6_by_2, 10_by_2, 12_by_2) if the back button is pressed, but I don't know how to do this given that *which* trial is the previous trial will depend on how randomization works. Thanks in advance for any help!
