For me at least, the invoice images are too muddled to equate with what you're saying. Looks like maybe a repeated header of some type but with no data. Check your query to see if the results produce duplicate header info but no other data. If it does, you can try DISTINCT ROW (as opposed to DISTINCT) or play with any table joins you might have in the query. If there is nothing wrong with the query, it must be a report design problem.
The more we hear silence, the more we begin to think about our value in this universe.
