For some reason you've made this much more complicated than it is. Just
select the nodes you want to total and apply the sum() function:

 
sum(//AwardFullData/AwardItemizedLine[count(./periodLinePeriodNumber)&lt;1]/
transactionAmount"/>

I'm assuming here that transactionAmount does actually hold a numeric value.
You haven't shown your source document, but there's a possible hint later in
your question that suggests trasactionAmount might hold a currency sign. If
that's the case then in 2.0 you can do

sum(//AwardFullData/AwardItemizedLine[count(./periodLinePeriodNumber)&lt;1]/
transactionAmount/
       number(translate(.,'$',''))"/>

There are several reasons this is wrong. Firstly, any expression of the form
$ADDME[XXX] is going to select a subset of the nodes in $ADDME. These are
AwardItemizedLine nodes, whereas you want to sum transactionAmount nodes.
Secondly, $TEST is taken as true if
//AwardFullData/AwardItemizedLine/transactionAmount selects any nodes, and
as false if it doesn't; the value doesn't depend in any way on the
AwardAtomizedLine node in question.

At this point I think we need to see what the data looks like.

A general comment: you're trying to do this by trial and error, which isn't
a very good way of learning the language. The stylesheets you're working
with aren't very well written, so learning from them isn't a good idea
either. Take some time to read a good XSLT book.
