We are getting the following error on line 5 of the following script;

Uanble to get property 'value' of undefined or null reference
function initPart() {
	if (!(prepop)) {
		loadValues("seclevel", "getseclevels.asp?sl=" + document.getElementById("selSecLevel").value);
		loadLookup("Priority", "ROUTINE");
		loadLookup("Releasability", "");

function validateCreate() {
  var classuri = document.getElementById("classuri");
  if (classuri.value == 0) {
    showError("Error - This field is mandatory and must be completed - Activity");
    return false;

My knowledge of Javascript is minimal so any help would be great.

Assuming that line 5 is:
loadValues("seclevel", "getseclevels.asp?sl=" + document.getElementById("selSecLevel").value);

one can only suspect that document.getElementById("selSecLevel") is returning a null reference, i.e. it cannot find an element with that id.
