JavaScript - No Js Errors But Not Working In Only Ie?

Hi

I am doing validation on a form, but instead of throwing an alert on empty fields I want to highlight those fields indicating error. if all are empty, then i would like to show only 1 generalized error
message "Pls. fill the highlighted textboxes.".
how do i do this and thanks in advance.

here is the link where the problem persist
http://www.ornusweb.com/what_we_done.html

I have mixed 2 scripts the light box script(lightbox.js) and scroller script(scriptaculous.js)

the page only works with ie and in other browsers it opens as an image(light box wont work)

the errors say

1st error> uncaught script.aculo.us requires the prototype javaScript frame work >1.4.0
scriptaculous.load
(anonymous function)

2 error > uncaught typeErrorbject function object(){[native code]} has no method 'extends'
(anonymous function)

can some one help me solve these problem's

The validator showed up these errors on my site.
They are from a script, but I know very limited javascript to correct it, to me it seems to be OK.

1. Line 15, Column 23: character "<" is the first character of a delimiter but occurred as data

for (var i = 0; i < d.length; ++i) {

This message may appear in several cases:
* You tried to include the "<" character in your page: you should escape it as "&lt;"
* You used an unescaped ampersand "&": this may be valid in some contexts, but it is recommended to use "&amp;", which is always safe.
* Another possibility is that you forgot to close quotes in a previous tag.


2. Error Line 15, Column 23: StartTag: invalid element name

for (var i = 0; i < d.length; ++i) {

Code:

<script type="text/javascript">
  window.onload = function() {
    if (!NiftyCheck()) {
      return;
    }
    Rounded("div#nifty", "#666", "#FFF", 30, 30);
  }
  function adjustRadius() {
    d = getElementsBySelector("div.rounded");
    for (var i = 0; i < d.length; ++i) {
      d[i].parentNode.removeChild(d[i]);
    }
    var x = document.getElementById("radiusx").value;
    var y = document.getElementById("radiusy").value;
    Rounded("div#nifty", "#666", "#FFF", x, y);
    return false;
  }
</script>

Does anyone know why these errors are coming up on the WC3?

i get this error when ever i try to process the form:

There was a SyntaxError: Unexpected token < error due to an parsererror condition.
