/**
 * Implementation of hook_comment
 */
function comment_cck_comment(&$comment, $op) {
  switch ($op) {
    case 'insert':
    case 'update':
	$node = node_load($comment->nid]);
...

to

/**

 */
function comment_cck_comment(&$comment, $op) {
  switch ($op) {
    case 'insert':
    case 'update':
	$node = node_load($comment[nid]);
...
