$tireqty = $HTTP_POST_VARS['tireqty'];
$oilqty = $HTTP_POST_VARS['oilqty'];
$sparkqty = $HTTP_POST_VARS['sparkqty'];

?>
<html>
<head>
<title> Bobs auto Parts - Order Results</title>
</head>
<body>
<h1>Bobs Auto Parts</h1>
<h2>Order Results</h2>

<?php

echo '<p>Order Processed at ';

<?php
echo '<p>Your order is as follows: </p>;

Change

PHP Code:


			
echo '<p>Your order is as follows: </p>;

to

PHP Code:


			
echo '<p>Your order is as follows: </p>';

( Note the added apostrophe )

I just thought it was worth pointing this out.

<?php
$myString = "99";
// $2 = "Two dollars"; // This is wrong
echo $myString . " red balloons for only $2<br />";
echo "$myString red balloons for only $2<br />";
echo '$myString red balloons for only $2<br />';
?>

Will output:

99 red balloons for only $2
99 red balloons for only $2
$myString red balloons for only $2

Because php will read within " double quotes looking for variables whereas it will not look inside ' single quotes. However, because php is brilliant it knows that variables cannot begin with a number so it will not attempt to use $2 as a variable and you will get an error if you un-comment the variable line.
