JS error UndefinedID in function preventing content loading

Hello group, I have an issue with JS on specifically the contact us pages or Contact 7 form pages in our website. Using Firefox error console I can see an error on the page which I assume will keep the banners from dropping down, the widgets from loading, and contact form from sending emails. I am not a JS coder so would love some input from the group. The function is below. The specific call is: if (id.length == 0 && name.length != 0) {

function InitMisc() {
  $j('#content input, #content textarea').each(function(index) {
    var id = $j(this).attr('id');
    var name = $j(this).attr('name');
    if (id.length == 0 && name.length != 0) {
      $j(this).attr('id', name);
    }
  });

  $j('#main label').inFieldLabels();

  $j('.rule span').click(function() {
	  $j.scrollTo(0, 1000, {axis:'y'});
	  return false;
 });
}
