Ah, thanks very much for that. Simple!
Uh oh. Doing as suggested leads to another issue indicating that what I’d like to do may not be possible.
If I change the email field to “not required” and the form is submitted without an email address it does not generate an email notice to our own designated email address.
So it looks like CF7 must have a “required” email address to work as intended.
Thank you again for the speedy advice. If you can think of another way (besides using a different plugin) that we can accomplish our goal it would be most welcome…CF7 seems like a very good plugin otherwise.
Best wishes!
