Having problems uploading files in PHP

[hiddeninclouds]

Hello all,
I've got a problem with a script i'm working on. I'm attempting to upload a file and data used to index the file. The errors i'm gettings are:

Warning: move_uploaded_file(/public_html/records/Babbage_engine.jpg): failed to open stream: No such file or directory in /home/towerpub/public_html/config/admintasks.inc on line 349

Warning: move_uploaded_file(): Unable to move '/tmp/php2vb2MO' to '/public_html/records/Babbage_engine.jpg' in /home/towerpub/public_html/config/admintasks.inc on line 349

Warning: chmod(): No such file or directory in /home/towerpub/public_html/config/admintasks.inc on line 350

The section of code causing problems:

function addsubmit()
{
	// load html file
	$this->display = new Template();
	$this->display->set_file("page", "htmltemplates/addsubmit.html");
	$this->display->set_block("page", "block", "main");
	$this->filepath = "/public_html/records/" . $_FILES[addfile][name];
	$this->recorddesc = $_POST['desc'];

	// check for all fields
	if(($_POST['injury'] == "NEW") && (is_null($_POST['newinjury'])))
	{
		// missing new injury
		$this->displaytext = "Form missing new injury";
		
	}
	elseif (is_null($_POST['desc']))
	{
		// missing description
		$this->displaytext = "Form missing description";
	}
	elseif (is_null($_FILES['addfile']))
	{
		// missing file
		$this->displaytext = "Form missing file";
	}
	elseif (file_exists($this->filepath))
	{
		// bad file name
		$this->displaytext = "File name already exists";
	}
	else
	{

		if ($_POST['injury'] == "NEW")
		{
			$this->injury = $_POST['newinjury'];
		}
		else
		{
			$this->injury = $_POST['injury'];
		}
		chmod($_FILES['addfile']['tmp_name'], 0755);
		move_uploaded_file($_FILES['addfile']['tmp_name'], $this->filepath);
		chmod($this->filepath, 0755);

		
		// connect to database

		$this->connection = mysql_connect($this->dblocation, $this->dbname, $this->dbpass) or die(mysql_error());
		$this->dbsel = mysql_select_db($this->database, $this->connection) or die(mysql_error());

		// add record
		$this->sql = "insert into records VALUES (NULL, '$this->recorddesc', '$this->filepath', '$this->injury')";
		$this->result = mysql_query($this->sql, $this->connection) or die(mysql_error());
	

	

		$this->displaytext = "Record Added <br> Injury:   $this->injury <br> $this->recorddesc";
		
	}	
	
	$this->display->set_var("message", $this->displaytext);
	$this->display->parse("main", "block", FALSE);
	$this->display->pparse("OUT", "page");
	exit;
}

Anyone see the problem?
