ct/productId]


Problem
-------
I am trying to get a list of the products that are listed in the <products>
node that are also in the <commission/product> node... The way I have above
works.. but it seems to be very slow... I am working with a large amount of
data... but I was curious if there was a better way?   $earnerId would be
the current earner I am trying to calculate totals for... Thanks very much
for any help!!
