contact form 7 dynamic text database

Hi there

Contact form 7 is really awesome plugin with many necessary features. I am using the following:

Contact form 7
contact-form-7-to-database-extension
contact-form-7-dynamic-text-extension.1.0.4.2
wp ecommerce
wp ecommerce custom field

What I need to do:
Have a form in the product page, send the form to a user whose email address will be in the custom field.

I have added the custom field which is email address while creating product. In the contact form, I have used hidden dynamic text and I am able to get the value in it. I didnt check mail function as I am trying in local host. All values are being submitted to DB, I am able to check using database under contact, except recepient email. Below is the form code. Any idea?

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

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

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

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

<p>[submit "Send"]</p>
