Problem in notification settings

Hello,

I have a contact form that allows a user to contact a functional manager (treasurer, webmaster, secretary, president, etc.) with the following fields:

Enter your: Last name, First name

Enter your email address:

Enter the manager’s email address: (Dropdown list with email addresses for each manager to choose from)

Message area and “Send” button

I’m having trouble configuring the notification settings.

I would obviously like the notification to also go to the manager’s email address, but I don’t see it in the settings (list of available fields). The only options offered are the admin and the user’s email address.

Do you have any ideas?

Thank you!
