// The form's <form...> tag needs to contain this attribute:
//        onsubmit="javascript:return RecordFormInformation();"

// Put this JavaScript somewhere below the form.

// Two variables in this JavaScript can be customized.

// Customizable variable 1:
// Between the quotation marks, specify the form name:
// var FormName = "form1";

// Customizable variable 2:
// Between the quotation marks, specify the cookie name:
var CookieName = "FormRestoreCookie";
