Uncaught ReferenceError

Hey,

I’m using gravity forms with your plugin and when its enabled I get a “refrenceError”.
This because of the following code:

<script type="text/javascript">
    jQuery(document).ready(function($){
        var gforms = '.gform_wrapper form';
        $( gforms ).submit(function() {
            $('<input>').attr( "type", "hidden" )
                .attr( "name", "gf_zero_spam_key" )
                .attr( "value", "(V8lhSU3eHr" )
                .appendTo( gforms );
            return true;
        });
    });
</script>

Personaly it think it something with the jquery version difference. but the (“value”, “(“) isn’t helping either…
