Hello, I have created a form for internal use and would like for the users of the form to be able to manually type in the email address that the form should be sent to each time they submit the form, as the person(s) who should be receiving the form will vary greatly. Is there an easy way to do this? Thank you!

 Have a field where the user types in the email address.

On the email submit data connection for the TO use the function button and select the email field you created in the first step.
