How to use jquery validation errorplacement for only one error field

Question

I am using jQuery validation to validate a form. My form is slit up into sections. The top part of the form, which has normal inputs, the validation error messages are being placed exactly as I want them.

My issue is that a specific error label that is placed in a different section will not display. I was told to try our the errorplacement function, but I do not see how I can use this with one specific error message.

errorPlacement: function(error, element) {

}

In my code below, you will see two HTML comments. The first one is to illustrate that if I move the input there, then the error message will display. The second comment is where the input is currently and where I actually want it, but it will not display there.

The input's id is #interestHidden.

Does anyone see how I can use errorplacement for just this one error message?

See my code below

<section class="sec90">
            <h3 class="subTC">Enter your information below.</h3>
            <form action="" id="salesforce_submit" method="POST" enctype="multipart/form-data">
                <div><input id="first_name" placeholder="First Name*" class="input block" maxlength="40" name="first_name" type="text"></div>
                <div><input id="last_name" placeholder="Last Name*" class="input block" maxlength="80" name="last_name" type="text"></div>
                <div><input id="company" placeholder="Company*" class="input block" maxlength="40" name="company" type="text"></div>
                <!-- Moving it here will allow the message to display -->
        </section>
        <section class="sec90">
                <h3 class="subTC">What are you interested in?*</h3>
<!-- Moving it here, it doesn't show -->
                <div><input type="hidden" id="interestHidden" name="interestHidden" value=""></div>
                <div id="interestWrap">
                    <div class="interest">

Attempt:

errorPlacement: function(error, element) {
            if(element.attr("id") == "interestHidden") {
                error.html('#interestError');
            } else {
                //Placement for other interest Hidden
            }
        },

Updated JS:

$('#salesforce_submit').validate({
        ignore: [],
        //ignore: "",
        rules: {
            first_name: {
                required: true,
                minlength: 2
            },
            last_name: {
                required: true,
                minlength: 2
            },
            email: {
                required: true,
                email: true

            phone: {
                required: true,
                //digits: true,

                alphanumeric: true
            },

            },
            interestHidden: {

            }
        },
