pass ID of record to a custom page

pass ID of record to a custom page

Hi,

I have a custom page where I display more detailed information of a record, plus information from other linked tables.
What I would like but can't find:

A link in the list view of a report (for each record) eg 'more info...' which links to a custom page, passing the ID of that record so that I can fetch the record in the custom page.

How can I achieve this?

Thanks,
Peter
