[Plugin: Contact Form 7] Checkbox Issue – Sending Selected Box Info

I know this question has been asked on the forum before, however I cannot seem to find the correct way to do this.

The checkbox data (Form) is not carrying over into my email(Message Body):

My Form looks like this:

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

<p>Company Name
[text company-name] </p>

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

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

<p>Web Site
[text web-site] </p>

<p>Phone
[text your-phone] </p>

Select the services you are interested in:

[checkbox Services “Web Site Design” “Web Hosting” “Web Analytics” “Search Engine Optimization” “Search Engine Marketing” “Social Media Marketing”]

<p>[submit “Send”]</p>

And my Message Body looks like this:

[your-name] from [company-name] is interested in the following services:

[Web-Site-Design]
[Web Hosting]
[Web-Analytics]
[Search-Engine-Optimization]
[Search-Engine-Marketing]
[Social-Media-Marketing]

[your-phone]

[web-site]

Any help getting the checkbox information to pass through and show up in my email would be greatly appreciated.
