Blog layout columns don't work

Hi,

I'm having this problem with blog layout option in my website. It just seems to break apart the page. and the columns are not working. You can see the problem at this link: www.saudilife.net/test.html

I've even selected the "Hide" option for "Intro text" in the parameters. Still neither the intro text gets hidden nor are the columns correctly displayed.

Please help.

Regards,
Faraz
