Thanks again Graham. I think you have given me an idea of the problem. The
solution is more complicated however, because adding that loop slows things
to a standstill in the database I'm using. Maybe I can use an if...
statement to arrange it so that this loop is only executed at the end of
each day? I only need the data on a daily basis.
