Center background image only appearing at the very top Options

[Holly1]

Hi everyone, first let me say what a very nice site this is. I'm hoping that someone might be able to help me. On our website www.PartyFavorWebsite.com we have a yellow image that used to appear in the center of our page all the way down to the bottom of the screen. It used to be shown behind our header and main image and was bordered on all of the edges by a pink background. I have attached a pic to show how it shold appear. Well yesterday the yellow image only appears at the very top of our page behind our header. Some of the html code shows now above it. I would like to get the image to display all the way down to the center again, along with removing the viewable code above the header. Can anyone please tell me what might be causing this? I know it must be something very minor, but I have checked the code and still cannot find the error. Any help would be greatly appreciated. Thank you in advance.

BTW my knowledge of html is extremely limited at best!
