<div dir="ltr">Hi David,<div><br></div><div>Thank you so much for your suggestions! I did try to do that but I am not sure how to let Eprime select a Random/Categorized BlockA and Categorized/Random BlockB, because I want 1/4 of participants to do BlockA randomly and then BlockB sequentially, 1/4 of participants to do BlockA sequentially and then BlockB randomly, 1/4 of participants to do BlockB randomly and then BlockA sequentially, and 1/4 of participants to do BlockB sequentially and then BlockA randomly. </div><div><br></div><div>Besides, the random list is not entirely random. I had to generate a randomized (with restrictions) list through Python and use it for every participant. So essentially the Randomized list is a sequential one.</div><div><br></div><div>Therefore, there are four lists: categorized BlockA, 'randomized' BlockA, categorized BlockB, 'randomized' BlockB. I want Eprime to select one Block A and one Block B, the two of which has opposite selections (one categorized, the other 'randomized').</div><div><br></div><div>Is it possible to be done through Eprime? Looking forward to your reply!</div><div><br><br>On Tuesday, August 19, 2014 11:46:21 AM UTC-4, McFarlane, David wrote:<blockquote class="gmail_quote" style="margin: 0;margin-left: 0.8ex;border-left: 1px #ccc solid;padding-left: 1ex;">You could achieve much the same effect, without
<br>any inline code, by using a main List with
<br>Selection Order set to Counterbalance, and Order
<br>By set to Subject. That List would have one row
<br>for each of your possible scenarios, and then use
<br>the Subject number to select which row to run.
