Iframe problem on JFBCLike

Hello,

I have an iframe overflow problem on JFBCLike (see www.caritation.com, below "parlons-en" on the right column).
I've tried to add "overflow:visible" on my div, but it only allow overflow at the bottom of the bloc, and not on the right.
Do you know where I should add "overflow:visible" to allow iframe to overflow on the right ?

To turnaround, I've tried to add JFBCLike to the popup page that appears when you clic on "faire connaitre à des amis". But it is not displayed. Any ideas ?

Sorry, I didn't give you the right link.
You can see this button on this page : www.caritation.com/index.php?option=com_...roupid=24&Itemid=581
You must be logged to see it.
I have tried to add "overflow:visible" but it doesn't work.

Fantastic ! It works.
It's nice to have great support from you.
Thanks.
