Thanks Robert. I was close before. I had tried something similar but just didnt get it straight. Have another question. I made the change to the code and the result is:
Your order was for the following:
Entree: ""
Dessert: "Ice Cream ($2)"
TOTAL BILL = $"0"
Now, for all variables do I put $_ before the variable? The rest of the code does not have this? But, That does not explain why the Course1 data was not displayed. Is it instead of Course1 it should be ListBox1?

Hi Wade,
This is what you should have put in the Echo Lines
echo 'Entree: "' . $_POST['Course1'] . '"<br>';
echo 'Dessert: "' . $_POST['ListBox2'] . '"<br><br>';
the $_POST variable is set as an array with the names of each of the POST
variables as Keys to the array. As such $_POST['Course1'] is the
replacement of $Course1.
Keep on trying.

I thought I was starting to get it until I got to the last section.
Original code from the book:
<?php
$total = 0;
echo "Your order was for the following:<br><br>";
echo "Entree: $Course1<br>";
echo "Dessert: $ListBox2<br><br>";
foreach (array($Course1, $ListBox2) as $val)
{
if (ereg("[0-9]+", $val, $reg)) $total += $reg[0];
}
echo "TOTAL BILL = $" . $total . "<br>";
?>
I was brave and tried to make many changes but none worked. This is where I ended up:
<?php
$total= 0;
echo 'Your order was for the following:<br><br>';
echo 'Entree: "' . $_POST . $Course1 . '"<br>';
echo 'Dessert: "' . $_POST . $ListBox2 . '"<br><br>';
foreach (array($Course1, $ListBox2) as $val)
{
if (ereg('[0-9]+', $val, $regs)) $total += $regs[0];
}
echo 'TOTAL BILL = $"' . $total . '"<br>';
?>
The output for this last code is:
Your order was for the following:
Entree: Array
Dessert: Array
TOTAL BILL = $"0"
Enlighten me. Im trying hard to understand where to put things together.
Thanks

String concatenation?
Its a way ogf combining strings into one.
$string = 'Hello';
$string = $string . ' World';
echo $string;
would output 'Hello World'

Sean,
Thats a new one for me. In the line below, what does the " ' . $Entrees[0] . ' "> do?
The " . ", do they have some value or do they negate something?
echo '<option value="' . $Entrees[0] . '">' . $Entrees[0] . '</option>';
