1. How do I receive the mail from the forms on site to multiple mail id's.
2. Is there any way by which we can use this form carrying values from "Book It" button that can fill one field on click.
I hope your rating was not based on those two questions because you could had found the answer to them very easy if you had searched our forum or at least if you had posted them in it.
1 - Just add one Hidden Email field and define in it the additional emails addresses.
2 - You can use the plugin aiContactSafeLink to do that.
