Why can't I add another reply to email address on my notification email?

You can only choose 1 email field in the Reply-to option. I checked your form and I can see that a user can only enter 1 email address.

You can have multiple Reply-to email addresses by having a hidden email field that has a default value. Here's how:

1. Insert an "Email" field. Right click the field and then choose "Hide Field".

2. Click the "Default Value" button at the top toolbar and enter the email addresses separated by a comma and space.

3. After that, go to the Recipients tab of the Notification and change the "Reply-To" field. Choose the "Hidden Reply-To Email" field in the drop down.

That's it! Hope that helps. If you have any questions, let us know. Thank you.
