Here is what I want to do:

1. I want a script that allows me to enter find mode to allow me to search for a contact, using a search for first and last name (the script I have for this works -- it's on a button).

2. Next I want Filemaker to enter that person's first and last name (information from two separate fields from the Contact layout) into a portal on a different layout (the Conference layout) to indicate that they are participating in a specific conference.

How do I do this?

Hi,

From what I understand, you should have 3 Tables, Contacts, Conference and Attendance.

What you need is to pull the contact ID and the Conference ID into the Attendance Table.

What you need is a relation from Contact Table to Attendance.

But your post does not mention any ID at all, and it is confusing how you will select the contact from the found records, and how you'd select later the conference you're targetting.

In any case, if your relation does allow creation of related record, it could be as easy as

Define Field [ Attendance::ConferenceID ; YourSelectedConferenceID ]
