Problems with scroll

[Valentina]

Hello,
I have embedded a Nabble forum into a website.
Here it is the link http://www.tuscanlife.it/prova/blog%20cucina%20-%20copy2.htm
The problem is, as you can see, that the nablle pagehas'nt a scroll, and so it is cut, without having the possibility to scroll down to see the rest of the page.
I have used a placeholder and put the nabble html code inside: below the html code
Blog di cucina
<script src="http://blog-di-cucina.395.n7.nabble.com/embed/f1"></script>What can I do to obtain the scroll function?
Thank you
Valentina
