thank you peterdeed, but you don't rest on Sunday? I downloaded and tried your changes, unfortunately I still have problems. the project I wrote with reportico has 7 reports, 5 work, in the sense that queries do not give problems, the only error, rather important for me is that they do not generate pdf, html and csv work correctly. 2 reports, on the other hand, very similar to each other, give two errors, the first just recalled the report, the second in querying a crtiteria
. the errors I have you can see them in the attached file. I repeat, I don't know if it just depends on reporting or how I generated the fields of some tables recalled in the report. I await your directions. thank you again for your great availability.
