Would a snapshot of the Query the report is based on help?
It's not going to hurt to have the query.
Open the query in design mode
Change the view to SQL
Copy and paste the text that is shown in the SQL view into the reply box here.
In the reply box, select the entire SQL and then click the <CODE/> button in the formatting bar above (or manually place [code] at the start and [/code]at the end of the SQL text).
It would also be helpfull to know which version of the Access you're using (2003?).
