Ok thanks very much for this,I will try out the combo box of all surnames. Thanks for the piece of code, I think I probably set it up wrong initially as well as I have the report looking at a query for the data and not a form? I use a form which comes from the same query to input the data but view it through the report for printing etc. Should I link the report to the form, or to the query that the form (and the report) is based on do you know?
Thanks
