![75937-a01-report-services-error-01.jpg][1] [1]: /answers/storage/attachments/75937-a01-report-services-error-01.jpg One last problem. Where I have drills on reports the group levels are not formatting according to the custom functions being used to colour the text and set the fonts. If I set the color to red the text will come out red. Is there any known problem with report where the calls to custom assemblies does not work for the group level headings? I am guessing it is an upgrade bug. Thanks and Best Regards Peter
