Opera problem with iframe

Hey All,

I am working on a site and have a problem with an iframe when I look at the page in oprea. instead of being transparent its white, as well as having a drop down menu above it go behind the iframe:

I have been able to get an iframe to work before in Opera, ie. http://www.secondhandrock.com/home.htm

so I don’t know what the problem is, any help would be appreciated, thanks!
