if you need the iframes to be resized according to the current page size, then you don't need a javascript to do so... just use the frameset, define height percentage for each frame, and list the frames inside it ... like this:

<frameset rows="20%,20%,20%,20%,20%">
  <frame id="leftFrame" src="f1.htm">
  <frame id="rightFrame" src="f2.htm">
  <frame id="rightFrame" src="f3.htm">
  <frame id="rightFrame" src="f4.htm">
  <frame id="rightFrame" src="f5.htm">

Open in new window

Define this function in the admin.htm script section:

function setFrameSize(theFrame){
    var theDoc = top.frames[theFrame.name].document;
    theFrame.style.height = (Math.max(
        Math.max(theDoc.body.scrollHeight, theDoc.documentElement.scrollHeight),
        Math.max(theDoc.body.offsetHeight, theDoc.documentElement.offsetHeight),
        Math.max(theDoc.body.clientHeight, theDoc.documentElement.clientHeight)

call that function like this for the IFRAMEs that you want to resize:
<IFRAME id=Cat1 style="WIDTH: 100%; HEIGHT: 300px" name=Cat1  onLoad="setFrameSize(this)" marginWidth=0
marginHeight=0 src="admin_files/addCat.htm" frameBorder=1></IFRAME>
