Multiple CKEditor Save button not working.

Hi,

I build my editor with the CKEditor builder at the official site.
This is how i implemented CKEditor:

[HEAD]

<script type="text/javascript" src="/ckeditor/ckeditor.js"></script>

[/HEAD]

[BODY]

<form action='index.php' method='post'>

<textarea class='ckeditor' name='a'></textarea>
<textarea class='ckeditor' name='b'></textarea>
<input type='submit' name='submit'>

</form>

[/BODY]

And the Save button is active i can press it but nothing happens, if i use the original submit button it works. 

What did i do wrong? 

Any help is greatly appriciated.
