how to get update page to work?????

i am working on an admin. and i have a page where it shows all of the members that have been inserted into the database through a form. the page has a delete column where you can delete members, which i have working, and i have an update column, the page which i need help on.
when i click on the update link, it goes to the update page,and the form fields are supposed to have the members information side of them so that you can change the information. the fields do not do that, and i’m not sure why. the only field that shows information is the member id field.
if anyone could help me out in getting this update page to work, then that would be appreciated. here’s the code i’m using below.

[code=php]
session_start();
do_html_header(‘Administration’);
error_reporting(E_ALL ^ E_NOTICE);
$tblname = “members”;
$host=”localhost”;
$dbuser=”mwooten1″;
$dbpass=”****”;
$database=”higgins”;
mysql_connect($host,$dbuser,$dbpass);
mysql_select_db($database) or die (“Unable to select database”);
$user_name = “”;
$user_email = “”;
$staddress = “”;
$city = “”;
if (isset($_POST[‘memberid’])){
$user_name = (isset($_POST[“user_name”]) ? $_POST[“user_name”] : “”);
$user_email = (isset($_POST[“user_email”]) ? $_POST[“user_email”] : “”);
$staddress = (isset($_POST[“staddress”]) ? $_POST[“staddress”] : “”);
$city = (isset($_POST[“city”]) ? $_POST[“city”] : “”);

if (!get_magic_quotes_gpc()) {
$user_name=addslashes($user_name);
$user_email = addslashes($user_email);
$staddress = addslashes($staddress);
$city = addslashes($city);
}
}
else
{
$memberid=(isset($_GET[‘id’]) ? intval($_GET[‘id’]) : “”);
if ($memberid) {
$query=”SELECT * FROM $tblname WHERE memberid='”.$memberid.”‘”;
$result=mysql_query($query);
$row=mysql_fetch_array($result);
if ($row) {
$user_name=$row[‘$user_name’];
$user_email = $row[‘$user_email’];
$staddress = $row[‘$staddress’];
$city = $row[‘$city’];
}
else {
$memberid=””;
echo “<h3>Invalid ID</h3><a href=”showmembers.php”>Return to Show Members</a>”;
}
}
}
if (isset($_POST[‘submit’])) {
$sql = “UPDATE $tblname SET user_name='”.$user_name.”‘, user_email='”.$user_email.”‘, $staddress='”.$staddress.”‘, city='”.$city.”‘”;
$sql.=” WHERE memberid='”.$memberid.”‘”;
$result = mysql_query($sql) or die (mysql_error());
echo “<h3>Record Updated!!</h3><a href=’showmembers.php’>Back to Show Members</a><br><br>”;
}
else
{
echo “<h3>Information has not been submitted Yet!</h3><a href=’showmembers.php’>Back to Show Members</a><br><br>”;
}

if ($memberid) {
$table_output='<table border=”0″ cellspacing=”2″ cellpadding=”2″>’;
$table_output.='<form action=”edit2.php” method=”post” enctype=”multipart/form-data”>’;
$table_output.='<input type=”hidden” name=”memberid” value=”‘.$memberid.'”>’;
