this code looks fine to me....
rather than highlighting, i would enclose the code in code blocks or php blocks, ie
PHP Code:
define('EMAIL_SEPARATOR', '------------------------------------------------------');
define('EMAIL_TEXT_SUBJECT', 'Inquiry from '. STORE_NAME );
define('EMAIL_TEXT_SALUTATION', 'Dear ' );
define('EMAIL_TEXT_NEWCUST_INTRO', "\n\n" . 'Thank you for stopping by ' . STORE_NAME . ' and considering us for your purchase. ');
define('EMAIL_TEXT_CURCUST_INTRO', "\n\n" . 'We would like to thank you for having shopped at ' . STORE_NAME . ' in the past. ');
define('EMAIL_TEXT_BODY_HEADER', 'We noticed that during a visit to our store you placed ' . 'the following item(s) in your shopping cart, but did not complete ' . 'the transaction.' . "\n\n" . 'Shopping Cart Contents:' . "\n\n" );
adding all of the highlighting for this post strikes me as problematic when trying to debug.
how about just posting line 21 exactly as it is in your script?
best.
