Report Filters on Pages

Report Filters on Pages

Hi
I have a Page with a stateless form and a report. The report is filtered on a value entered in the stateless form. The page is shown using openURL and passing parameters. All works fine except that I don't want to show the filtered field in the report (it's an ID). If I delete the ID field from the report the filter fails. I can hide the field when the page is shown by clicking the eye icon but I don't want my users to have to do that. So can I hide the ID field but still use it to filter?
