So I basically want a text that will load one letter at a time. And this what I have and it's not working. I know very little JavaScript so could someone please help me?

<script type="text/javascript" language="JavaScript">
<!--

setTimeout("document.write('a')",200);
setTimeout("document.write('b')",200);
setTimeout("document.write('o')",200);
setTimeout("document.write('u')",200);
setTimeout("document.write('t')",200);
setTimeout("document.write(' ')",200);
setTimeout("document.write('u')",200);
setTimeout("document.write('s')",200);

// -->
</script>
