In “Mail” tab if you see following details
In the following fields, you can use these mail-tags:
[text-455][email-604][text-456][textarea-356]
these control id’s which is used in “Form” tab like this [email* email-604], here for email I have used “[email-604]”
so, Reply-To my code will be as follows
Reply-To: [email-604]
and error is gone.
Hope this will help.
Happy coding ??
