"Cannot modify header information" problems!!

Hi!I have a small problem thats driving me crazy and i'm unable to figure out what is casuing the "Cannot modify header information" error I am getting when I submit data to my database.
The exact error is: <b>Warning: Cannot modify header information - headers already sent by (output started at /home/itsnota/public_html/music/register_employee.php:1) in /home/itsnota/public_html/music/register_employee.php on line 53</b>
I have checked my code over and over again but can't find what is causing the problem. Can anyone help me out?
The code:
<?php require_once('Connections/conn_music.php'); ?>
<?php
function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = ""
{
$theValue = (!get_magic_quotes_gpc()) ? addslashes($theValue) : $theValue;
switch ($theType) {
case "text":
$theValue = ($theValue != ""
? "'" . $theValue . "'" : "NULL";break;
case "long":
case "int":
$theValue = ($theValue != ""
? intval($theValue) : "NULL";break;
case "double":
$theValue = ($theValue != ""
? "'" . doubleval($theValue) . "'" : "NULL";break;
case "date":
$theValue = ($theValue != ""
? "'" . $theValue . "'" : "NULL";break;
case "defined":
$theValue = ($theValue != ""
? $theDefinedValue : $theNotDefinedValue;break;
}
return $theValue;
}
$editFormAction = $_SERVER['PHP_SELF'];
if (isset($_SERVER['QUERY_STRING'])) {
$editFormAction .= "?" . htmlentities($_SERVER['QUERY_STRING']);
}
if ((isset($_POST["MM_insert"])) && ($_POST["MM_insert"] == "frmRegisterEmployee"
) {$insertSQL = sprintf("INSERT INTO userdata (userID, Name, EMail, Address, Postcode, Username, Password, RegistrationDate, RegistrationIP) VALUES (%s, %s, %s, %s, %s, %s, %s, %s, %s)",
GetSQLValueString($_POST['userID'], "text"
,GetSQLValueString($_POST['Name'], "text"
,GetSQLValueString($_POST['EMail'], "text"
,GetSQLValueString($_POST['Address'], "text"
,GetSQLValueString($_POST['Postcode'], "text"
,GetSQLValueString($_POST['Username'], "text"
,GetSQLValueString($_POST['Password'], "text"
,GetSQLValueString($_POST['RegistrationDate'], "text"
,GetSQLValueString($_POST['RegistrationIP'], "text"
);mysql_select_db($database_conn_music, $conn_music);
$Result1 = mysql_query($insertSQL, $conn_music) or die(mysql_error());
$insertGoTo = "index.php";
if (isset($_SERVER['QUERY_STRING'])) {
$insertGoTo .= (strpos($insertGoTo, '?')) ? "&" : "?";
$insertGoTo .= $_SERVER['QUERY_STRING'];
}
header(sprintf("Location: %s", $insertGoTo));
}
?>

What usually causes this error is basically an output happening before the header() funtion. So check in you include script to find out if there's a blank line at the end or an echo or print. If you have anything being displayed before the header() function then this error message will always appear.
