How to add a field to the Confirmation Email?

ZenCart Confirmation Email.
I am trying to add a line to the email sent out for order confirmation.
I made the following changes.
I should see "This is your Ticket", but all I see is "EMAIL_TICKET_1"
The email works fine, but does not find the proper text.
What am I doing wrong?

email/email_template_checkout.html
added at end of CSS:
.ticket {background-color:#FF6600; border:1px #9a9a9a; width:542px; height:200px; padding:2px; font-size:10px; }
added at end of HTML:

includes/languages/english/checkout_process.php
added after line 42:
define('EMAIL_TICKET_1', 'This is your ticket');

admin/orders.php
added after line 124:
$html_msg['EMAIL_TICKET_1'] = str_replace('\n','',EMAIL_TICKET_1);

I am using Zencart 1.3.9 and Sophie Blue template
What am I missing?
Thanks

Use the developers tool kit to look up another "constant" that is default to ZenCart - -
See the places that it is defined and insure that your new constant "$EMAIL_TICKET_1" is added to all of the places required

admin/orders.php

Order confirmations aren't handled via the admin side. So editing that file isn't going to accomplish your stated goals.
For the emails sent to the customer when they are placing their order, you'll need to edit the send_order_emails() method of the /includes/classes/orders.php class file.

Thanks for the answer. It solved my problem.
I am now continuing with adding a ticket to the email.
I am impressed with the size of the forum, and the speedy answers.

I created an admission ticket which is mailed out following the confirmation email.
I would like to add seat allocation, but I need the quantity of seats remaing at the time of sale.
Do I have to read the database from table 'Products' and field 'products_quantity' or are they accessible in the system?
All I need is 'products_ quantity' and I can figure out the rest.
The function 'zen_get_products_stock' seems to get the item I want, but I don't know how to use it?
Does the call go in includes/classes/orders.php?
I am using ZenCart 1.3.8 and Sophie Blue template.
Take a look at:

If you want to buy a seat, use the dummy credit card code 4030000010001234 CCV 123
