Yes, nice suggestion. Even though I read the book I found it hard to
set up multiple random lists. (Once I had it figured out, it was easy.)
I also ran one where I needed to establish a random order for each
subject, then repeat that same "random" order later in the experiment.
Wound up solving that problem awkwardly, then got great suggestions
from this list.<br>

<pre wrap="">Many thanks to Leisha, and to David Hairston who suggested the same
approach.
It worked first time :)
Does anyone else think this functionality would be a useful addition to the
available Selection Order properties of a list? e.g.. I would have a
weighting of 5 for each of the six items, and an Selection Order
specification called say, "Random, confined', would produce the selection
order detailed below.
Thanks again
Tony.

<pre wrap="">I think you have a master block list that lists your 6 lists and is set
to select Randomly. Each of the 6 lists in the master list has its 5
trials embedded in it, and those embedded lists are set to select
Randomly, and also to go through all 5 trials before returning to the
master list. Similarly, the master list goes through all 6 of its
embedded lists before terminating.
