Hi Doug,
It is difficult for us to work out what is happening as we don't have
access to a toy data set that we can play with. Excel spreadsheets are one
of those things that you can't just attach to your email to the help list.
If there is somewhere you can leave a _small_ Excel sample file (take the
first 10 rows, say) that we can download (Google Drive, Dropbox?) and
include the URL in your email, maybe someone can offer more than guesses.
