At the moment, the XPath you're using translates as:

a transamount element that is a child of
  a fsatrans element that is a child of
    a flexact element that is the document element

You want only those transamount elements that are a child of a fsatrans
element that has a transtype child whose value is 'Claim'.  Conditions like
this are known as predicates, and you put them in square brackets after the
node that you're placing the condition on.  In your case "a fsatrans
element whose a transtype child whose value is 'Claim'" translates to the
step:

  fsatrans[transtype = 'Claim']

So if you use the XPath:

  /flexact/fsatrans[transtype = 'Claim']/transamount

you will get only the 'Claim'-type transamounts.

As an aside, if you're using this within a stylesheet, you could possibly
use the built-in sum() function from XPath and the format-number() function
from XSLT rather than a new function:

  format-number(sum(/flexact/fsatrans[transtype = 'Claim']/transamount), 
                "$###,##0.00")

I hope that helps,
