function getQueryStringValue(param) {
        qryString = window.location.search.substring(1);
        qryParmas = qryString.split("&");
        for (i = 0; i < qryParmas.length; i++) {
            params = qryParmas[i].split("=");
            if (params[0] == param) {
                return params[1];
            }
        }
        return null;
    }
