RizB on "[Plugin: Dreamgrow Scroll Triggered Box] required="required""

Hi there,

I have three questions.

1) My popup signup has two required fields, e-mail and a checkbox, like so...

<input id="email" name="Email" required="required" type="text" value="Email Address" />

<input name="Disclaimer" required="required" type="checkbox" value="Disclaimer" />

http://www.theabe.tv/about-us/

However, when completing the form, validation is only requested for the checkbox. If you check the checkbox, the form can be submitted without an e-mail field being filled. How can I make both fields compulsory?

2) Also, can you please tell me how I change the subject field of the e-mail I receive - currently I receive this...

Dgd Scrollbox submit on Australian Business Executive | A Deeper Look at Business & Government

I want to customize this completely.

I have added <input name="subject" type="hidden" value="Signup with theabe.tv" /> to my form but this appears to be ignored.

3) Finally, how can I add more than one recipient of these signup's under "Send submitted values to email"? I have added two e-mail addresses, separated by a comma, but submitted forms are only sent to the second e-mail address.

Thank you.
