Custom actions on a published report

Custom actions on a published report

Hi

I have a publicly available table report with a custom action which opens a summary report.

The summary report has all navigation and functions turned off.

The issue I have is that the summary report only displays the last record, not the summary linked to the record which was selected.

I tried using the advice in this discussion thread:  https://help.zoho.com/portal/en/community/topic/how-to-define-openurl-function-with-id-of-current-record

But the person clicking on the custom action needs to be a logged in user which is not an option for me.

Any advice would be gratefully received.

Thanks
