--------^^^^^^^^  surely not?

so they're Record/Reseller_ID/CLI/COMPLETED_SETUP's? It always helps to show
your xml.

does that mean, outside the above loop but in the same context as the loop?
If you're having to do <xsl:for-each select="Record/Reseller_ID"> then your
context is the parent of Record. If in that context you then ask for
"../CLI/COMPLETED_SETUP" then from what little glimpse of your xml you've
given us you're probably getting an empty node-set, unless the parent of the
the parent of Record also have CLI/COMPLETED_SETUP children...

How about summing "Record/Reseller_ID/CLI/COMPLETED_SETUP" instead? But this
is all mere conjecture, without knowing the contexts :)

what does your xml look like?
