Contact Form 7 – Trouble with check boxes

I have installed and set up Contact Form 7

Everything is up on my site.

My issue is with the checkbox option.

I am able to check either/or box testing the contact form, but do not get an answer for the question in the email.

Here is how my form is set up:

<p>Your Name (required)
[text* your-name] </p>

<p>Your Email (required)
[email* your-email] </p>

<p>Subject
[text your-subject] </p>

<p>Your Message
[textarea your-message] </p>

Check the box below if you would like to join my monthly Newletter (required)
[checkbox* your-choice exclusive “Yes” “No Thanks”]

Can anybody show me the proper steps in order to have the answers show up in my email so I can tell what answers were submitted in the contact form?

Thanks!
