HELP - php code to post all list box values

[metse]

'am a newbie & am busy designing a site that has simple order-form which captures details of a cust and submit them throuth as an email using php, which works fine.

 

my problem is i added 2 list boxes, one(as a drop-down) pre-populated with items-to-order which allows the user to add items in-need to the second list box...

 

how do i sumbit all values of the 2nd list box along as an email. My code currently is:

.

.

$listbox2 = $POST('listbox2')

.

.

$message .= "items on order are: ";

$message .= $listbox2;

.

.

 

which doesn't work.

 

Please Help !!!!
