The next time you call GetRes, it will return the value of width.

The ideal way would be to grab the width and set the table's width via
the DOM, for example:
 width = GetRes()
 document.getElementById("theIDofTheTableYouWant").style.width = width
Or
 width = GetRes()

document.getElementByTagName("TABLE").childNodes.item(0).setAttribute("w
idth",width)

Or you could write it in the document like so:
<script type="text/javascript">document.write(GetRes())</script>
