CMS Made Simple Forums

I need to insert this code for meteo in a page:

<!-- Inizio codice ilMeteo.it -->
<__iframe width="450" height="340" scrolling="no" frameborder="no" noresize="noresize" src="http://www.ilmeteo.it/box/previsioni.ph ... "></__iframe>
<!-- Fine codice ilMeteo.it -->

I don't know the right way to do it. I red about smarty tag {embed..} but I can't. I'm very new to CMSMS.
Can you help me?

Thank you very much.

Try this:
Place this tag {embed header=true} in your header and this where you like it.
{embed url="http://www.ilmeteo.it/box/previsioni.ph ... ink=1773C2"}

It's fine but I've some problems with height of the iframe.
Here is the page:

http://www.alda-amelia.it/meteo-cattolica

You have to add to your css file
#myframe {
height: 400px;
}
or other height you want.
