<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>The easiest way to do this is probably to
use Nested lists, e.g. create 1 List for each of your 12 groups that you want
to present. You then have 12 entries on your Block level list that correspond
one to each group. Create an attribute on the Block level list (e.g.
“StimList”) which contains the name of the list you want to use/associate
with each group (e.g. List1, List2, List3, …, List12).
Then on the Trial level list specify [StimList] in the Nested column and set
the Weight to 12. This setup will randomly choose a set of
stimuli to use and then run 12 sequential trials using the chosen “StimList”
to provide the trial stimuli.</span></font></p>

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>Take a look at the NestingRT example
included as an E-Prime sample experiment to see how Nesting can be
used. The main difference between that example and what you want to
do is that the example has the names of the nested lists specified explicitly,
whereas in your experiment you want to specify the name of the nested list as
an attribute [StimList]</span></font></p>
