Input Parameters on Notification email script

Can I use input parameter in an email script?

I have this code on my notification's body

HTTP Status: ${u_notes}

${mail_script:ErrorReportNotificationScript}

<mail_script>errorReport(${u_notes});</mail_script>  

And this on my Email Script

(function runMailScript(/* GlideRecord */ current, /* TemplatePrinter */ template, /* Optional EmailOutbound */ email, /* Optional GlideRecord */ email_action, /* Optional GlideRecord */ event) {

	function errorReport(status){
		if (status >= 400 && status < 499) {
			template.print("<p>Client Error!</p>");	
		} else if (status >= 500 && status< 599) {
			template.print("<p>Server Error!</p>");	
		} else {
			template.print("<p>Error!</p>");	
		}
	}
	

})(current, template, email, email_action, event);

I know that the code is not working but i put the code here just for an simple representation
