Can you help?


I have an Access 2003 DB which is 90% complete
I have a problem with running a Report based on a query?
(the query is a "Total" query based on 12 other query's - e.g. 12 individual items are "looked up" in a table containg costs x qty in Text Box then Total Query finds all 12 results) The Query works 100% & the form based the same query works 100% - but when i use the same "Total" Query for the reports it stops working when the table > 300 records? (i have duplicate querys / tables / reports all of which function correctly with < 300 records) Not sure if i have explained this very well?
