<div dir="ltr">Thanks, David.<br>The structure I have is a bit different, it looks either like this:<br><br>SessionProc
<br> BlockList

<br></div><div style="margin-left: 40px;">BlockBTrialLIst <br><div style="margin-left: 40px;">BlockBProc
<br></div></div> <br>or if I try using one BlockProc for both lists and specify it only at the BlockList level, then it looks like:<br><br>SessionProc
<br> BlockList <br><div style="margin-left: 40px;">BlockATrialList<br></div><div style="margin-left: 40px;">BlockBTrialLIst <br>BlockBProc

<br>
<br>I must be missing something, because I cannot see what's wrong
<br>here. I imagine that you have a structure like
<br>
<br>SessionProc
<br> BlockList
<br> BlockAProc
<br> BlockATrialList
<br> BlockBProc
<br> BlockBTrialLIst
<br> ...
<br>
<br>(there are actually better ways to structure this (e.g., using a
<br>single BlockProc, and using an attribute to select the trial List),
<br>but this is how most beginners would do it).
<br>
<br>In that case, if you set Order of BlockList to Random, and Order of
<br>each BlockXTrialList to Sequential, then E-Prime will present your
<br>blocks in random order, but trials within each block in sequential
<br>order (I have students practice this in my online course).
<br>
<br>What am I missing?
