Formatting in custome receipt text

Hi there - I'm adding a custom header to the Order Confirmation email customers receive to replace the generic "thanks for shopping with us" message, but I'm having trouble with the formatting.

In includes/languages/english/checkout_process.php, I've tried to use <br> tags to separate lines (and put a space between the greeting header and the "details of your order" line), but they're being ignored.

Here's the code:

define('EMAIL_THANKS_FOR_SHOPPING','This confirms your Sacred Fools Online Box Office transaction. For show tickets, be sure to arrive on time as late seating cannot be guaranteed.<br><br>Sacred Fools Theater<br>660 N. Heliotrope Ave<br>(S. of Melrose, between Normandie & Vermont)<br><br>Limited parking available next to the theater. Note parking restrictions.<br><br>Questions/concerns (310) 281-8337 or see our website at www.SacredFools.org<br>');
define('EMAIL_DETAILS_FOLLOW','The following are the details of your order.');

I want it to look like this in the receipt:

**This confirms your Sacred Fools Online Box Office transaction. For show tickets, be sure to arrive on time as late seating cannot be guaranteed.

Sacred Fools Theater
660 N. Heliotrope Ave
(S. of Melrose, between Normandie & Vermont)

Limited parking available next to the theater. Note parking restrictions.

Questions/concerns (310) 281-8337 or see our website at https://www.SacredFools.org

The following are the details of your order.**

Instead, it looks like this:

This confirms your Sacred Fools Online Box Office transaction. For show
tickets, be sure to arrive on time as late seating cannot be
guaranteed.Sacred Fools Theater660 N. Heliotrope Ave(S. of Melrose, between
Normandie & Vermont)Limited parking available next to the theater. Note
parking restrictions.Questions/concerns (310) 281-8337 or see our website at
https://www.SacredFools.org
The following are the details of your order.

Any help appreciated. Thanks!

You need to use ' . "\n" . ' instead of ```
<br>

Awesome, thanks for helping a PHP newbie.

So the below code would be correct?  (Single-quotes placed next to each other marked in red for ease of distinguishing from actual double-quotes...)

**define('EMAIL_THANKS_FOR_SHOPPING','This confirms your Sacred Fools Online Box Office transaction. For show tickets, be sure to arrive on time as late seating cannot be guaranteed.' . "\n" . '' . "\n" . 'Sacred Fools Theater' . "\n" . '660 N. Heliotrope Ave' . "\n" . '(S. of Melrose, between Normandie & Vermont)' . "\n" . '' . "\n" . 'Limited parking available next to the theater. Note parking restrictions.' . "\n" . '' . "\n" . 'Questions/concerns (310) 281-8337 or see our website at <https://www.SacredFools.org>' . "\n" . '');**

Thanks again!

That's the concept.

How's it working for you ?
