I'm trying to figure out why my page is not working as expect (even though it was working previously). 

Here is the page:
<http://www.taconic.com/resources/webinars/archive/hla-transgenic-mice-development-validation-and-applications.html>

The functionality on this page was set as such when you submit the form, the contact goes away and the video displays - using a URL parameter. 

Here is my JS (and style code for this page):

```
    <style>
    .dynamic-content {
        display:none;
    }
    </style>
    <script src="//code.jquery.com/jquery-1.12.0.min.js"></script>
    <script type="text/javascript">
        // Parse the URL parameter
        function getParameterByName(name, url) {
            if (!url) url = window.location.href;
            name = name.replace(/[\[\]]/g, "\\$&");
            var regex = new RegExp("[?&]" + name + "(=([^&#]*)|&|#|$)"),
                results = regex.exec(url);
            if (!results) return null;
            if (!results[2]) return '';
            return decodeURIComponent(results[2].replace(/\+/g, " "));
        }
        // Give the parameter a variable name
        var dynamicContent = getParameterByName('webinar');

         $(document).ready(function() {

            // Check if the URL parameter is hla
            if (dynamicContent == 'yes') {
                $('#yes').show();
            } 
            // Check if the URL parmeter is empty or not defined, display   default content
        else {
            $('#default-content').show();
        }
    });
</script>

```

On Submit the form redirects the user to <http://www.taconic.com/resources/webinars/archive/hla-transgenic-mice-development-validation-and-applications.html?webinar=hla>.
