Hello.  

The code below is causing the color selection image to appear behind the drop-down box, so that it says "Percent" on top of the colors.

<script>
function getInfoAndUpdate()
{
   if (isNaN(formNumRows.value))
   {
      alert ("The rows field can only contain numbers");return;
   }
   else if (isNaN(formNumCols.value))
   {
      alert ("The colums field can only contain numbers");return;
   }
   var callerWindowObj = dialogArguments;
   callerWindowObj.rtNumRows = formNumRows.value;
   callerWindowObj.rtNumCols = formNumCols.value;
   callerWindowObj.rtTblCellspacing = formCellspacing.value;
   callerWindowObj.rtTblCellspadding = formCellspadding.value;
   callerWindowObj.rtTblAlign = formTblAlign.value;
   callerWindowObj.rtTblWidth = formTblWidth.value + formTblWidthtype.value;
   callerWindowObj.rtTblBorder = formTblBorder.value;
   callerWindowObj.rtTblBgColor = Bgcolor.value;
   callerWindowObj.rtTblBrColor = Brcolor.value;
   callerWindowObj.createTable();
   window.close();
}
</script>
<script language=JavaScript>
<!--

function MM_findObj(n, d) { //v3.0
  var p,i,x;  if(!d) d=document; if((p=n.indexOf("?"))>0&&parent.frames.length) {
    d=parent.frames[n.substring(p+1)].document; n=n.substring(0,p);}
  if(!(x=d[n])&&d.all) x=d.all[n]; for (i=0;!x&&i<d.forms.length;i++) x=d.forms[i][n];
  for(i=0;!x&&d.layers&&i<d.layers.length;i++) x=MM_findObj(n,d.layers[i].document); return x;
}

function MM_showHideLayers() { //v3.0
  var i,p,v,obj,args=MM_showHideLayers.arguments;
  for (i=0; i<(args.length-2); i+=3) if ((obj=MM_findObj(args[i]))!=null) { v=args[i+2];
    if (obj.style) { obj=obj.style; v=(v=='show')?'visible':(v='hide')?'hidden':v; }
    obj.visibility=v; }
}

function show(val2) {
Bgcolor.value = ' bgcolor="'+val2+'"';
B3.style.backgroundColor = val2;
}
function showM(val3) {
Brcolor.value = ' bordercolor="'+val3+'"';
B2.style.backgroundColor = val3;
