Josh, I am using Forms 2.0 and the embed code accordingly. And yes, there is custom CSS on the page, but only to position the form.
Kenny, the reason that I am embedding the form instead of just pulling it onto the page is because in IE 8, the form floats up and out of place. I thought that by embedding the form and using CSS styling to keep it in place, it might be a better way to have clean rendering across browsers. Is there another way to solve this?
