Writing a Top Ten App

I am writing an app to make a top ten list.  The people can rate each team 1 to 10.  What I want to do now though is make it so they can only vote for 1 team for each rating.  You can only vote one team as number 1 one team as number 2 etc until you get to ten.

This is what I have so far.  It only checks to see if you have voted for the team not the rating you gave them though.

 dim conn
 dim rs
 dim teamId
 dim visitorIP
 dim rating
 dim cookie
 dim cookieRated

 teamId = Request.Form("teamId")
 rating = Request.Form("rating")
 visitorIP = Request.ServerVariables("REMOTE_ADDR")
 cookie = Request.Cookies("rate_" & teamId)

 set conn = Server.CreateObject("ADODB.Connection")
 set rs = Server.CreateObject("ADODB.Recordset")
 
 conn.Open "DRIVER={Microsoft Access Driver (*.mdb)}; DBQ=" & Server.MapPath("????????")
 rs.ActiveConnection = conn
 
 if cookie = "" then
  cookieRated = false
 else
  cookieRated = true
 end if

 if rating = "" then
 'Invalid rating
 %>
  <font face="Verdana" size="2" color="black">
   <h2 align="center">Invalid Rating</h2>
   <p align="center">You must select a rating first!<br><br>
   <a href="javascript:history.go(-1)" style="text-decoration: none">Go Back</a>
  </font>
 <%
 else
 'Valid rating, make sure visitor hasn't already voted
 'by checking the ratings table
 
  rs.Open "SELECT COUNT(*) FROM ratings WHERE ip='" & visitorIP & "' AND teamId=" & teamId
  
  if rs.Fields(0).Value = 0 then
   if cookieRated = false then
    'Visitor hasn't rated yet, let's add it
    conn.Execute "INSERT INTO ratings(rating, ip, teamId) VALUES(" & rating & ", '" & visitorIP & "', " & teamId & ")"
    Response.Cookies("rate_" & teamId) = true
    Response.Cookies("rate_" & teamId).expires = Date() + 30
    %>
     <font face="Verdana" size="2" color="black">

      <h2 align="center">Thank You For Rating!</h2>
      <p align="center">Your Team rating has been added to our database.<br><br>
      <a href="showteams.asp" style="text-decoration: none">Continue</a>

    <%
   else
    'Visitor has already rated this article

     <h2 align="center">Already Rated</h2>
     <p align="center">You have already rated this teams!<br><br>

     <h2 align="center">Already Rated</h2>

     <a href="javascript:history.go(-1)" style="text-decoration: none">Go Back</a>

   </p>

 end if

I would appreciate any help. Thanks

In the database I have Ip address recorded for who has voted the rating and the team that they rated.

Is there not a way to check the IP and see if he has given another team the rating he is trying to sumbit.  I think it has to do with an If then statement but not sure how to write it.

For example if he has already rated a team number 1 then it will return you have already given out this rating.

Here is the link to what the frontend looks like
http://www.p-15.com/Team_Ratings/showteams.asp

I failed to mention it but I am Also using cookies.  The code at the beginning shows it and is setup to keep people from voting more than once for a team.  I just want to limit a little further so you can not give the same ranking twice. 

I do appreciate the advice
