I'm coding a jsp page that checks for cookies and tries to run a javascript function when it detects that a certain cookie exists. I did some debugging and find that the session and cookie and be extracted and displays correctly. However, when try to test the web page on my browser, the function isn't called and the bottom left displays an error:

Line: 31
Char: 2
Error: Object Expected
Code: 0

My codes are as follows:

Code:
<%@ page language="java" import="java.util.*"%>
<%

	String LoginID = request.getParameter("id");
	if(LoginID == null)
	{
		response.sendRedirect("login.jsp");
	}
	else
	{
		session.setAttribute("Current", LoginID);
		out.println(LoginID);
		out.println(session.getAttribute("Current"));
	}
	
	String cookieName = LoginID;
	Cookie cookies[] = request.getCookies();
	Cookie myCookie = null;
	String container = "";

		if (cookies != null)
		{
			for (int i = 0; i < cookies.length; i++) 
			{
				out.println(cookies[i].getValue());
				if (cookies [i].getName().equals (cookieName))
				{
					myCookie = cookies[i];
					out.println(myCookie.getValue());
					break;
				}
			}
		}
		else
		{
			myCookie = null;
		}
