Onetone theme contact form jumps

Hi there,

I have a problem with my Onetone contact form. It jumps when I someone wants to fill out the form. It works, but only when one knows where to click. How can I solve this problem?

This is my code:

<p style=”text-align: center; color: ##ffffff”>Vul je gegevens in en AKC neemt zo spoedig mogelijk contact met je op.</p>
<div class=”contact-area”><form class=”contact-form” action=”” method=”post”><input id=”name” tabindex=”1″ name=”name” size=”22″ type=”text” value=”Naam” placeholder=”Name” />
<input id=”email” tabindex=”2″ name=”email” size=”22″ type=”text” value=”” placeholder=”Email” />
<textarea id=”message” tabindex=”4″ cols=”39″ name=”Bericht” rows=”7″ placeholder=”Bericht”>Message</textarea><input id=”sendto” name=”sendto” type=”hidden” value=”[email protected]” />
<input id=”submit” name=”send” type=”button” value=”Verzend” /></form></div>

Cheers,
Anne
