New to FileMaker, been working with sql-based databases before and can't really get my head around a few things.

A basic contact register: You've got a contact layout and a portal with phone numbers, an unlimited number. I've got the relationships setup etc.

One of these phone numbers is the primary, so you got a checkbox. But only one of these can be set at a time. So when the user checks one, all the other have to go unchecked, for that particular contact.

How do you do that?

Much obliged.

Martin

I store the ID of the preferred phone in the Contact record. I script the checkbox to set the ID.

So when the user checks one, all the other have to go unchecked, for that particular contact.

Strictly speaking is this a radio button metaphor not a check-box ditto....

But Barbera's suggestion is otherwise succinct and to the point correct.

I can only agree that Barbara's solution is very good. I might say the same about you're language, where'd you learn the word succinct?

Bad example, but learning how to do this with a script I feel will be useful, I'm sure of it. What if you have two primaries? (The example is really flawed now). Or better yet, a user determined number of primaries? Can it be done?

Camitz, two primaries? Certainly, Soren will post a link to a dictionary, lol.

I think that you are alluding to the fact that you'd like to go down a list and "mark" records. This technique of adding and removing record IDs from a global field can be found here: Multi-user Marking .

But Barbara used, the old Jeff Almquist way ... why not exploit a very usefull CF in this context:

...since your solution often can benefit from it in various methods you wish to throw after a solution.
