>TKS I'll check these things. But I can tell you how I made this report. I use the table and created a report with the wizard based on that table. Thats why I find it strange that I selected the field in the wizard and it shows it to me in preview mode but when it comes time to print VFP claims it can't find the field.

It probably stores TableName.FieldName as field expression. It's much better not to have explicit table name in the report, e.g. use just fieldexpression.
Get rid of the table name (using frx as a table, also don't forget to make a backup first :))
