i have a database created by Access 97. i converted it to Access 2002. Everything is working fine. it has a Label for mailing list. when i want to print these mailing list it says "Enter Parameter Value" "Trim". but it doesnt say that on Access 97.
It sounds like a query was made to manipulate the data for placement on the label. To check, look where the report finds it's data source. If it is a query, look in the criteria row for anything that is entered.
Or a calculated field may have been created using the Trim function. If their is no field to Trim an error would result.
