Free extensions for Joomla!

Good afternoon!!!
I liked very much of this module!! It is great.

But I put 2 tabs in my site, and in each tab I put a persistence different from the module "Acconrdion front page core".
This module accordion front page core that he is xhtml valid, and your module also, but when I do what I described above, I do not manage it validates in the site of the W3C (http://validator.w3.org).

I receive the next error:

Validation Output: 1 Error

1. Error Line 407, Column 10: ID "accordian" already defined

<div id = "accordian" class = "corenews">

✉

An "id" is the unique identifier. Each team this attribute is used in the document it must have to different value. If you plows using this attribute them the hook will be style sheets it may be lives appropriate use it to you classes (which group elements) than id (which plow it used you identify exactly one element).
2. Info Line 311, Column 9: ID "accordian" first defined here

<div id = "accordian" class = "corenews">

How can I repair that?
Thank you very much.
