[jQuery] Exists

[shapper]

Hello,

I have the following:

  if (subject == '---') {
    if(!$('label[for="Subject",class="Error"]').length) {
      $('#Subject').parent().after('<label for="Subject"
generated="true" class="Error">Required field</label>');
    }
  }

I need to check if a label with for="Subject" and class="Error"
exists:

if(!$('label[for="Subject",class="Error"]').length)

This is not working. What am I doing wrong?

Thanks,
Miguel
