not get mysql db data .... into html page with php (stumped) : I am working on an assignment, and it requires me to select a "slip_id" from the 3aStudent_Slip.html and pass it to the next html 4aservice_request.html and populate a table that is being built in the php code. I have NOT had any php classes so I am really struggling with why it's NOT getting any database from the "ProgrammingDatabase" on the server.

using the following code ... 

	<?php
		require_once('auth.php');
	?>

	</head>
	<body>
		<div id="innerWrapper">
	<h1>Service request by <?php echo $_SESSION['SESS_FIRST_NAME'];?></h1>

	<a href="index.php">Login Page</a> | 
	<a href="amenu.php">Menu Page</a> | 
	<a href="logout.php">Logout</a>

	<?php
	$slip_id = strtoupper($_POST['slip_id']);
	echo("<h2>Services for Slip ID $slip_id</h2>");

	//Verify Password
	$vlogin=$_SESSION['vlogin'];
	$vpassword=$_SESSION['vpasswd'];

	//Connection String
	$con=mysql_connect("localhost", $vlogin, $vpasswd);

	if(!$con)
	{
		die("Could not connect".mysql_error());
	}

	//Select Database
	mysql_select_db("ProgrammingDatabase", $con);

	//The actual SQL code goes below into the structured variable $result
	$result=mysql_query("SELECT * FROM service_request");

	//Constructing the table and column names
	echo "<table border='1'>
	<tr>
	<th>Service ID</th>
	<th>Description</th>
	</tr>";

	//Looping until there are no more records from $result
	//If there are records, print the column for that row
	//do the while loop below with the variables from $result

	while($row=mysql_fetch_array($result))
	{
		echo "<tr>";
		echo "<td>".$row['service_id']."</td>";
		echo "<td>".$row['description']."</td>";
		echo "</tr>";
	}

	echo "</table>";

	//Close the SQL connection string
	mysql_close($con);

	?>
