Q88 How can I change the location of two frames using a simple '<a href="">'?

<script language="JavaScript"><!--
function functionName(fileName1,fileName2) {
    parent.frameName1.location.href = fileName1;
    parent.frameName2.location.href = fileName2;
}
//--></script>

<a href="javascript:functionname('file1.html','file2.html')">Go</a>
