I have created a report that spreads over 4 pages containing 1) covering letter, 2) certificate details 3) certificate summary 4) invoice. In order to get the report to work i had to create grouping as the report content was too high for the detail section. This works fine.
However, i now need to add a subreport to show details of any certificate endorsements on the certificate page (2). The subreport looks like a datasheet subform and works as intended. However, when i link the subreport to the main report by Cert_ID and run it i get an error message "the expression is typed incorrectly or is too complex to evaluate".
If i use "DoCmd.SendObject acSendReport, "Client Certificate", acFormatPDF" then access crashes.
Is it possible this is happening because for some reports there will be no records in the subreport?
Or am i better off starting the whole report from scratch?
