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

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>';
