[jQuery] Accordion in IFrame

Hello,

I am working with DotNetNuke and the Accordion widget from JQuery.
The problem is that the DNN-page is loaded in an IFrame so i cannot
acces the accordion.

<div class="dvFrame">
<iframe class="IFrame" marginheight="0" marginwidth="0"
frameborder="0" runat="server" id="frmDNN" ></iframe>
</div>

The contents of the IFrame is loaded dynamically.
I have tried to acces it this way:
$(""#frmDNN #accordion"").accordion({ header: ""h3"" });
and many other ways, but still can't find the solution if it excists.

So can someone help me with this.

Thanx in advance...
