I have a div that starts off as hidden. I want it to slide in to a fixed size on click.

It is used in a graph, the size-in is for effect.

Where t is the finished size for top
where w is the finished size for width
and h is the finished size for height.


<div id="Layer1" style="position:absolute; left:102px; top:<cfoutput>#t#</cfoutput>px; width:<cfoutput>#w#</cfoutput>px; height:<cfoutput>#h#</cfoutput>px; z-index:1; visibility:hidden;">
 <table width="100%" height="100%">
  <tr>
    <td class="expired">&nbsp;</td>
  </tr>
</table>
</div>

at the moment I snap it in by using
<a href="#" onClick="Layer1.style.visibility='visible';"><img name="transperantcfm_r1_c2" src="fireworksimages/transperant.cfm_r1_c2.gif" width="420" height="19" border="0" alt=""></a>

any ideas???

The starting point is already good.
But you need a function for the move initialization and a second function for move steps.
You call the initialization function like this:

<a href="#" onClick="startMove('Layer1',100,200,300);return false;"><img name="transperantcfm_r1_c2" src="fireworksimages/transperant.cfm_r1_c2.gif" width="420" height="19" border="0" alt=""></a>

The initialization function looks like this:
<script>
var theDiv, dTop, dWidth, dHeight, tStep;
var xStep = 10;
var xFact = 10;
function startMove(divID,t,w,h){
  theDiv = document.getElementById(divID);
  dTop = t;
  dWidth = w;
  dHeight = h;
  theDiv.style.visibility="visible";
  tStep = setTimeout("doMove()", xStep);
}

// and this is the stepper move function:

function doMove(){
  var xT = dTop - theDiv.offsetTop;
  var xW = dWidth - theDiv.offsetWidth;
  var xH = dHeight - theDiv.offsetHeight;
  if(xT+xW+xH!=0){
    theDiv.style.top = theDiv.offsetTop+(xT/xFact);
    theDiv.style.width = theDiv.offsetWidth+(xW/xFact);
    theDiv.style.height = theDiv.offsetHeight+(xH/xFact);
    tStep = setTimeout("doMove()", xStep);
  }
}
</script>

I see it sliding, but of course first after inserting some visible text:
<td class="expired">&nbsp;Here Some Text</td>
