skal stemme 2 gange før det virker

Jeg har tidligere lagt dette spørgsmål op, men uden at få svar, så jeg prøver lige igen. Jeg har lavet en afstemning, men jeg skal stemme 2 gange, før jeg får resultatet af afstemningen at se. Kan det være et cookie-problem eller er der kodet forkert et andet sted. Se her:

<?php
  global $cookieprefix;
  if(isset($_REQUEST['action'])) {
    if($_REQUEST['action'] == "vote") {
      $conn = mysql_connect ("xxxxxxxx","xxxxxxxx","xxxxxxxx");
      mysql_select_db("boldsens_dk");
      mysql_query("UPDATE pollanswer SET hits = hits+1 WHERE questionid = '$_REQUEST[questionid]' AND id = '$_REQUEST[id]'");
      mysql_close($conn);
      setcookie($cookieprefix."stem", "true", time()+999999);
    }
  }
?>

<?
          function HaveVoted() {
            global $cookieprefix;
            if($_COOKIE[$cookieprefix."stem"]) {
            return true;
            } else {
            return false;
            }
            }
                                 
function ShowResults() {

########## POLL QUESTION ##########

$kode .= "<table>\n";
$conn = mysql_connect ("xxxxxxxx","xxxxxxxx","xxxxxxxx");
mysql_select_db("boldsens_dk");
$result = mysql_query("select * from pollquestion WHERE start <= now() AND end >= now()");
while ($row = mysql_fetch_array($result)) {
$kode .= "<tr><td colspan=\"2\">" . htmlentities($row["question"]) . "</td></tr>\n";

$questionid = $row["questionid"];
}

########## SUM OF POLLANSWERS ##########

$result = mysql_query("select sum(hits) as hits from pollanswer where questionid = '$questionid'");
while ($row = mysql_fetch_array($result)) {
  $sum = $row["hits"];
}

$result = mysql_query("select * from pollanswer WHERE questionid = '$questionid'");
while ($row = mysql_fetch_array($result)) {
  $percent = 0;
  if($row["hits"] > 0) {
    $percent = ($row["hits"] * 100) / $sum;
  }
    $kode .= "<tr><td>" . htmlentities($row["answer"]) . "</td>";
    $kode .= '<td><img src="Pics/bar.jpg" style="width: ' . $percent . 'px; height: 12px; border: 0px;" alt=""></td>';
    $kode .= "<td>" . round($percent , 1). "%</td></tr>\n";
}
  $kode .= "<td><tr><td colspan=\"2\">$sum stemme(r) i alt</td></tr>\n";
mysql_close($conn);

$kode .= "</table>\n";

########## VOTE ##########

if($_REQUEST[action] == "vote") {
$conn = mysql_connect ("xxxxxxxx","xxxxxxxx","xxxxxxxx");
  mysql_select_db("boldsens_dk");
  mysql_query("UPDATE pollanswer SET hits = hits + 1 WHERE questionid = '$_REQUEST[questionid]' AND id = '$_REQUEST[id]'");
  mysql_close($conn);
}
return $kode;
}

function ShowPoll() {
    ########## POLL QUESTION ##########
   
    $kode .=  "<form action=\"index.php?action=vote\" method=\"post\">\n";
    $kode .= "<table>\n";
   
    $conn = mysql_connect("xxxxxxxx", "xxxxxxxx", "xxxxxxxx");
    mysql_select_db("boldsens_dk");
    $result = mysql_query("select * from pollquestion WHERE start <= now() AND end >= now()");
   
    while ($row = mysql_fetch_array($result)) {
    $kode .= "<tr><td>" . htmlentities($row[question]) . "</td></tr>\n";
   
    $questionid = $row[questionid];
    }

    ########## POLL ANSWERS ##########
   
    $result = mysql_query("select * from pollanswer WHERE questionid = '$questionid'");
    while ($row = mysql_fetch_array($result)) {
    $kode .= "<tr><td><input type=\"radio\" name=\"id\" value=\"" . $row["id"] . "\">" . $row["answer"]."</td></tr>\n";
    }
    $kode .= "<tr><td><input type=\"hidden\" name=\"questionid\" value=\"$questionid\">\n";

    $kode .= "<br>";
    $kode .= "<input type=\"submit\" value=\"Stem\"></td></tr>\n";
    $kode .= "</table>\n";
    $kode .= "</form>\n";

    return $kode;
}

            if(HaveVoted() == true) {
            echo ShowResults();
            } else {
            echo ShowPoll();
            }
           
            if(HaveVoted() == true) {
                        echo "Du har stemt";
            } else {
                        echo "Du har ikke stemt";
            }
?>

Kan I gennemskue den?
