Thank you, Amy. I knew my method wasn't the most efficient. My problem
is trusting E-Prime to faithfully counterbalance the sample on subject
number.<br>

<pre wrap="">Harvey,
You can accomplish this with labels, but the List object is already set
up to permit counterbalancing by subject (On the Selection tab in the
List object properties pages). Counterbalance selects one sample from
the options based on the Order By value.
1. Create each version of your word lists as a separate List object in
Unreference E-Objects. Each word list should contain the same "Word"
attribute to hold the individual words.
2. Create a List in Unreferenced E-Objects for each version of the
experiment (i.e., each list of words).
3. Create a block level List that is set to counterbalance by subject
4. On the block level List, create an attribute (e.g., ListName) to
hold the names of the List objects in Unreferenced (your word lists).
5. On the TrialList, pass the name of the attribute holding the names
of the Lists in unreferenced (i.e., ListName) in for the Nested column
value.
6. Set the block level List to counterbalance by Subject number.
This will result in a single row being selected from the BlockList based
on the subject number, will assign the name of a specific wordlist to
ListName, and that List will be used to supply the words to the trials.
I hope this helps you get started. If you run into trouble, I would
suggest submitting a request to web support.
Amy

Subject: Re: Reading in stimuli from a file and using Labels
Thanks Leisha (and everyone else who replied). In order to put in a
label do I just create an Inline that contains the label and place it
just before the procedure or list I want to execute ?
