if($_POST['Submit']) {
// check email address

$error = "Invalid email address<br>";}

// display errors
if($error) {

<b>Error</b><br>
<?php echo $error; ?><br>
<a href="#" onClick="history.go(-1)">try again</a>


<?php
}
else
if($_POST["username"] && $_POST["password"] && $_POST["email"]) {
include ("functie.php");

verbind();


$sql = "SELECT * FROM leden WHERE username LIKE '$username' ORDER BY id DESC";
$resultaat = mysql_query($sql) or die(mysql_error());

if ($row = mysql_fetch_object($resultaat)) {
echo "sorry deze gebruikers naam bestaat al";
}

else {

$sql = "INSERT INTO leden (username, password, email)
VALUES ('$username', '$password', '$email')";
mysql_query($sql) or die(mysql_error());

<form action="toevoegen.php" method="post">
<table border="1" cellspacing="0" cellpadding="0" bordercolor="#000000">

<table border="0" cellspacing="0" cellpadding="5">

Ik denk dat hij zo moet...

<?php
if(file_exists('createadmin.php'))
{
exit("<h1>Loading error</h1>\n<p>You must delete <b>createadmin.php</b> first.</p>\n");
}

if($_POST['Submit'])
{
// check email address
if ((!ereg(".+\@.+\..+", $email)) || (!ereg("^[a-zA-Z0-9_@.-]+$", $email)))
{
$error = "Invalid email address<br>";
}
// display errors
if($error)
{
?>

<b>Error</b><br>
<?php echo $error; ?><br>
<a href="#" onClick="history.go(-1)">try again</a>
<?php
}
}
else
{
if($_POST["username"] && $_POST["password"] && $_POST["email"])
{
include ("functie.php");
verbind();

$sql = "SELECT * FROM leden WHERE username LIKE '$username' ORDER BY id DESC";
$resultaat = mysql_query($sql) or die(mysql_error());

if ($row = mysql_fetch_object($resultaat))
{
echo "sorry deze gebruikers naam bestaat al";
}
else
{

$sql = "INSERT INTO leden (username, password, email) VALUES ('$username', '$password', '$email')";
mysql_query($sql) or die(mysql_error());


echo "succesvol toegevoegd<br><br>";
echo "<a href=\"login.php\">Inloggen</a>";

}
}
else
{
?>

<form action="toevoegen.php" method="post">
<table border="1" cellspacing="0" cellpadding="0" bordercolor="#000000">

<table border="0" cellspacing="0" cellpadding="5">
