    Problems with PHP Adding Rows/Columns

    Code:
    <?php
    	require('includes/header.php');
    	
    ?>
    
    <h4> <ul id="menu">
    <li><p><a href="customer_details.php">Customer Details</a></p></li>
    <li><p><a href="order_customer_details.php">Details by order</a></p></li>
    <li><p><a href="country_list.php">Customers by Country</a></p></li>
    <li><p><a href="categories.php">Products by category</a></p></li>
    <li><p><a href="low_stock.php">Low Stock Items</a></p></li>
    <li><p><a href="index.php">Home</a></p></li>
    </ul></h4>
    
    
    <?php
    	$sql = "SELECT customers.CompanyName, orders.CustomerID, orders.OrderID, order_details.OrderID, order_details.ProductID, products.ProductID, products.ProductName, order_details.UnitPrice, order_details.Quantity, orders.shipVia, shippers.shipperId, shippers.CompanyName, orders.Freight
    	FROM customers, orders, order_details, products, shippers
    	WHERE customers.CustomerID = orders.CustomerID
    	AND orders.OrderID = '" . $_GET['order'] . "%'
    	AND orders.OrderID = order_details.OrderID
    	AND order_details.ProductID = products.productID
    	AND orders.ShipVia = shippers.ShipperID
    	ORDER BY products.productName, products.UnitsInStock, products.UnitPrice, shippers.CompanyName, orders.Freight";
    	
    	$result = mysql_query($sql) or die(mysql_error());
    
    	
    echo "<table border='1'>
    <tr>
    <th>Product Name</th>
    <th>Quantity</th>
    <th>Unit Price</th>
    <th>Shipper</th>
    <th>Shipping Cost</th>
    <th>Total Cost</th>
    </tr>";
    while($row = mysql_fetch_array($result))
      {
      echo "<tr>";
      echo "<td>" . $row['ProductName'] . "</td>";
      echo "<td>" . $row['Quantity'] . "</td>";
      echo "<td>" . $row['UnitPrice'] . "</td>";
      echo "<td>" . $row['CompanyName'] . "</td>";
      echo "<td>" . $row['Freight'] . "</td>";
      //echo "<td>""</td>";
      }
    echo "</table>";
    		
    ?>
    
    
    
    <?php
    require('includes/footer.php'); 
    
    ?>
    I want to multiply the quantity row by the cost row and add the Freight amount to it. Please help.

    PHP Code:


    $total 
    $row['Quantity'] * $row['UnitPrice'] + $row['Freight'];
