You can prepend or append any information to any named HTML element using JavaScript/jQuery. If you're using version 8 of SSI Web, below is the code that would allow you to add text before and after the element which has an ID of "next". In this case, I'm using jQuery because it is simple and cool to use. :)
<script>
$(document).ready(function () {
$('#next').before('This is text before the Next Button');
$('#next').after('This is text after the Next Button');
});
</script>
Just drop this code onto your page, such as the footer area, and it should work its magic.
