jQuery validation passwords never match...

jQuery validation passwords never match...

Hi,
I have this pretty simple html form which has two password fields. It is checked by jQuery Validation Plug-in but then I try to submit it I always get not matching passwords error...

Here is the passwords fields HTML:
  1.                         <label>
  2.                             <strong>3.</strong> Choose a Password <span>*</span><br />
  3.                             <input type="password" class="text" name="password" />
  4.                             <em>Must be at least 8 characters long.</em>
  5.                         </label>
  6.                         <label>
  7.                             Verify Password <span>*</span><br />
  8.                             <input type="password" class="text" name="confirm_password" />
  9.                         </label>
And this the part jQuery Validation Plug-ins rules:
  1. var validator =   $('#signup').validate({
  2.         rules: {
  3.             username: "required",
  4.             password: {
  5.                 required: true,
  6.                 minlength: 5
  7.             },
  8.             confirm_password: {
  9.                 required: true,
  10.                 minlength: 5,
  11.                 equalTo: "#password"
  12.             },
  13.             email: {
  14. ......
My mistake must be really obvious but I just can not notice it... any help please?
