Coding for the page is as follows: (My first fully validated page!! )

<map name="Header" id="Header">
<area shape="rect" coords="10.26, 1.10, 13.06, 1.69" href="testindex.htm" alt="Link to Home Page" />
<area shape="rect" coords="3.61, 0.98, 10.04, 1.68" href="HWS/HWS.htm" alt="Link to Hot Water Page" />
<area shape="rect" coords="10.26, 1.10, 13.06, 1.69" href="http://hia.com.au/" target="_blank" alt="Link to HIA Website" />
<area shape="rect" coords="10.99, 0.03, 11.97, 1.07" href="http://www.toolsforyourtrade.com.au" target="_blank" alt="Link to the Tools for your Trade website" />
