title: javascript ok/cancel dialog box appear once per session
body: <p>I am trying to get this to work in my iweb page hosted not on MobileMe. With the code below I continue to get the alert box on each refresh of the page instead of once per session. I am a total newbie here so be kind please.</p>
  
  <pre><code>//Alert message once script- By JavaScript Kit
  //Credit notice must stay intact for use
  //Visit http://javascriptkit.com for this script
  
  //specify message to alert
  var answer=confirm("Click OK if you have been cleared Sutter's HR department to start       
  volunteering.")
  if (answer)
   alert ("Excellent!!  Please select your dates directly within the scheduling calendar.")
  else
   alert ("Let's get to it then. Contact Ruth in HR at 576-4208 to schedule an appointment     so you can get started.")

    var search = Name + "="
    var returnvalue = "";
    if (document.cookie.length &gt; 0) {
      offset = document.cookie.indexOf(search)
      if (offset != -1) { // if cookie exists
        offset += search.length
        // set index of beginning of value
        end = document.cookie.indexOf(";", offset);
        // set index of end of cookie value
        if (end == -1)
           end = document.cookie.length;
        returnvalue=unescape(document.cookie.substring(offset, end))
        }
     }
    return returnvalue;
  }
