Reciprocal Validation between select field and text field about verifyjs

[jpillora]

Give this a try:

$.verify.addRules({
  cellphone: function(r) {
    //pass validation if there is no carrier
    if(!$("#carrier").val()) {
      return true;
    }
    //perform cell validation here [Note: r.val() is a shortcut to $(element-being-validated).val() ]
    if(/^\d{10}$/.test(r.val())) {
      return "You must enter a valid cell-phone number"
    }
    //passed
    return true;
  }
});

Now, we can use it

<form>
  <select id="carrier">
    <!-- dropbox options -->
  </select>
  <input value="" data-validate="cellphone">
  <input type="submit" class="submit">
</form>

I appreciate you taking the time to help!

I did try it but the fields didn't get flagged when I entered a cellphone number and left the dropdown select alone, nor did it work when I selected a dropdown option with valid, non-blank data and left the phone number blank.

Here's what I did code-wise:

<div class="clear"></div>
<div id="home_email_list">
    <div id="container"> <!-- http://psychostick.com/listmessenger/public/listmessenger.php -->
        <form method="post" action="test.php" name="subscribeform" class="pure-form pure-form-aligned">
