why is this table not showing up in this div? :(

Hi, this should be simple but I am rubbish at xhtml and css so I just can't see what I'm doing wrong! I really appreciate any help.

<div id="position1">
  <table width="630" border="0" align="center" cellspacing="5">
    <tr>
      <td colspan="3" align="center" valign="bottom"><div align="center"><br />
          <br />
            <img src="spring-header.png" alt="spring at umcwfb" width="488" height="90" /></div></td>
      </tr>

     etc etc....

  </table>
</div>

the css is very simple, it is:

#position1 {
	background-image:url(spring-bg.jpg);	
	background-position:center;
	background-repeat:no-repeat;
	width:700px;
	height:900px;
	overflow:auto;
	
}

nevermind - i found the problem. or rather, it found itself and after a second upload it all showed up.
