Background-image inside div not showing up

So I was working on this site and I had the displaying how I was wanting. After working on a lower page banner all of a sudden everything disappeared and all I was left with was the background Image in the Body.

Can you figure out why the topImage id does not display? It is frustrating as hell to see it work one second and then not the other:

<style>
   body
   {
   background-image:url("images/Background.gif");
   background-repeat:repeat-y;
   background-attachment:fixed;
   background-position:center top;
   }

   #topImage
   {
   position:absolute;
   background-image:url("images/Top-Banner.gif");
   background-repeat:repeat-x;
   width:100%;
   top:0px;
   left:0px;
   }
</style>

<body>

    <div id="topImage"></div>

</body>

Sorry if this a really basic question, I am kind of new at this.

#topImage doesn't have a height set, and no elements inside it which would give it a height.

#topImage
{
  position:absolute;
  background-image:url("images/Top-Banner.gif");
  background-repeat:repeat-x;
  width:100%;
  height: 100px; /* Change to the height you need */
  top:0px;
  left:0px;
}

Or just stick an img tag inside the div instead of using background-image, that would work as well.

try using the following syntax

#topImage
{
  position:absolute;
  background-image:url("../images/Top-Banner.gif");
  background-repeat:repeat-x;
  width:100%;
  height: 100px; /* Change it to auto if you need to div to adjust automatically according to contents inside it */
  top:0px;
  left:0px;
}

hope that sorts out the problem
