DaniWeb IT Discussion Community - Uploading with PHP error

I am trying to write a simple php program that will up load files smaller then 200000000 bytes to my website, but I keep getting an error when I try to run it
the initial HTML code is:

    <html>

<body>



<form action="upload.php" method="post"

enctype="multipart/form-data">

<label for="file">Filename:</label>

<input type="file" name="file" id="file" /> 

<br />

<input type="submit" name="submit" value="Submit" />

</form>



</body>

</html>

and then the following is the php code:

[code]
<?php
if (($_FILES["file"]["size"] < 200000000))
{
if ($FILES["file"]["error"] > 0)
{
echo "Return Code: " . $_FILES["file"] ["error"] . " ";
}
else
{
$Size = ($_FILES["files"]["size"]/ 1024);
if ($Size > 1000)
{
$Size= $Size/1000;
$type = "Mb";
}
else
{
$type= "Kb";
}

echo "Upload: " . $_FILES["file"]["name"] . " ";
echo "Type: " . $_FILES["file"]["type"] . " ";
echo "Size: " . $Size . " " . $type . " ";
echo "Temp file: " . $_FILES["file"]["tmp_name"] . " ";
if (file_exists("stuff/" . $_FILES["file"] ["name"] ))
{
echo $_FILES["file"]["name"] . " already exist. ";
}
else
{

move_uploaded_file($_FILES["file"]["tmp_name"], "upload/" . $_FILES["file"]["name"]);
echo "Stored in: " . "stuff/" . $_FILES["file"] ["name"];
}
}
}
else
{
header("Location: http://www.doled.org/upload/uhuh.html");
}
?>
[\code]

which when I run on line gives me the error
"Upload: balloon08.gif
Type: image/gif
Size: 0 Kb
Temp file: /usr/local/tmp/phpe96Gqh

Warning: move_uploaded_file(upload/balloon08.gif) [function.move-uploaded-file]: failed to open stream: No such file or directory in /home/.aspen/mesamb1/doled.org/upload/upload.php on line 32

Warning: move_uploaded_file() [function.move-uploaded-file]: Unable to move '/usr/local/tmp/phpe96Gqh' to 'upload/balloon08.gif' in /home/.aspen/mesamb1/doled.org/upload/upload.php on line 32
Stored in: stuff/balloon08.gif"

which makes no since to me and I would like to fix, any advice would be greatly appreciated
