jquery - MVC3/4 Validating Hidden Fields

I have set up model validation for my form but validation doesn't seem to work at all. I don't suppose anybody can help. I've tried using the below work-around but that keeps pulling up an 'undefined' error in firebug.

Example Work-Around Script:

<script type="text/javascript">
    $(document).ready(function () {            
        $.validator.setDefaults({ ignore: [] });
    });
</script>

Example Text Field (Note: autocomplete text field with name of customer):

    @Html.TextBox("txtCustomer", null, new { @id = "txtCustomer", @class = "txt" })

Example Hidden Field (Note: When selection is made from the autocomplete field, the id is injected into the hidden field):

    @Html.HiddenFor(model => model.Customer_ID, new { @id = "hCustomerID" })

Example Model Data Annotation

    [Range(1, Int32.MaxValue, ErrorMessage = "Please select a customer")]
    public int Customer_ID { get; set; }

EDIT: Screenshot of errors

Sorry i have to post links to the screenshots because my rep points are high enough.

Its too late to change the ignore on the validator in this way after the unobtrusive script. This is because the validator only pulls in the defaults once - when it is created. The unobtrusive script creates the validator for you. You need to reference the existing validator object and update it.

try this

<script>
    $(document).ready(function () {            
        $('form').validate().settings.ignore = []
    });
</script>
