Attribute value access

[Gary Klatsky]

In my experiment I have an attribute in the BlockList that determines which
attribute in the trial list is used based on subject number. The values in
the BlockList are the attribute names in the trial list. This works without
any problems.  The problem I am having is accessing the attribute value in
the trial list.  I am writing a script that displays that value in the
feedback display. Since the attribute name varies across subjects I want to
access it from the attribute in the BlockList. However when I try any
calculations of that value I keep getting a type mismatch error. Anyone have
any experience with accessing second order attribute values?

Thanks in advance
