<br>

<br>I'm not sure that we're talking about the same thing.  You refer to 

<br>three Lists, a master List with two sub-Lists.  I am talking about 

<br>only one List that has rows for both types of trials, differentiated 

<br>by what Procedure you put in the Procedure column of each row.  Does 

that make any sense?

<br>

<br>As for the rest...  You use IFIS, eh?  Sigh.  Don't get me started on 

<br>IFIS, we used that mess years ago and were glad to discard it, we 

<br>just do straight E-Prime now and are happier for it.  So I do not 

<br>care to sink my mind into all the IFIS nuances just now.  But I do 

<br>recall that IFIS puts a few control Lists down in Unreferenced 

<br>E-Objects, and you have to pay close attention to those because some 

<br>of those values will override the control values up in your E-Prime 

<br>design.  (Unless, of course, you have some newer and nicer version of 

<br>IFIS that I do not know about.)  (And if you search the group for 

<br>"IFIS", you may find further statements from me at
