That works perfectly, thank you!
I noticed that when I increase the number of Features (currently 119), the code mistakes larger numbers beginning with the same number (e.g. 60, 63, 67, 69, etc.) as one feature (i.e., Feature 6). When this happens, instead of presenting one feature and all the items in a random order, it presents a different feature (beginning with that number) each time along with a random item. This happens a few times per experiment.
Is there any way I can specify that the whole number (up to three digits) of Feature be taken into account?
Thank you in advance.
