[jQuery] Exists

[jQuery] Exists


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
