Contact Form Issue

Hello, I am running contact form 7 and having some issues submitting the form. I believe it may be a CSS issue.

The submit button on my form on https://tweetmyhome.com/tweet-my-home/ does not work unless you click the text NEXT to the check box. Clicking the checkbox itself will infact check the box, but will not activate the Submit button.

Here is the partial code from contact form 7 ‘<div class=”row”>[acceptance agree id:agree class:checkbox]<div>
<label class=”check” for=”agree”>I have read and agree to the Terms of Use.</label></div></div><div>
<div><input class=”submit” type=”submit” value=”Tweet My Home” /></div>’

If you go to the page and check it with Firebug you can see all of the classes around it.

I would appreciate it very much if someone could advise on how to fix this.

Thank you,

Jon
