Looking at your earlier posts I would suggest that yes it should be ListBox1
and not Course1.
Also change the foreach line to read
foreach (array($_POST['ListBox1'], $_POST['ListBox2']) as $val)
The $_ is only used for the Automatic Global Variables.

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?
