I have a portal set up that allows me to add a number of people who are assigned to an event.
When I add a person to the portal I would also like to be able to assign only one of them to be a primary contact.
My example portal has two fields and looks as follows:
NAME: PRIMARY Y/N:
Person 1 No
Person 2 No
Person 3 Yes
Person 4 No
What I'm wondering is how I go about ensuring that only one of these people can be assigned as the primary.
I've tried searching the forums for possible answers to this but haven't had any luck as yet. I'm sure this kind of question has probably been asked before but I'm not sure what search terms I should be using.
Any suggestions will be greatly appreciated : )
