Gee!  Why didn't you say that the first time? :{)}

Nope ... undo what I told you last time, since you are still working with 
all of the rows.

In this case I don't think position() is going to help you ... I suggest 
using count() as below.

It is important when working with XSLT to know that sometimes you need to 
approach problems without always using matching.  Other tools are available 
to examine the source node tree.

I hope this helps.
