Contacts DB with additional Portal on Contact Record showing a list of Appointments. The Portal shows an identical list irrespective of the Contact Record being viewed.

This works well but I would like each Appointment to show automatically on the relevant Contact Record via another portal or whatever.

To sum up, an Appointment shows on every Record until it is deleted but also shows permanently on the relevant Contact Record to which it relates.

I haven't a clue whether this can be done - help.

Take a look at Data4Life:

It's a free download and you can take it apart of use if directly if it fits your needs.
