wpsc-transaction_results_functions

I am working on editing the emails sent to the customer. All instructions I have read refrence wpsc-transaction_results_functions file that should be in plugins/wp-e-commerce/wpsc-theme/functions/
When I go there there that file is diferent from what I have in \themes\mytheme\functions
This block of code is not there

$message = apply_filters( 'wpsc_transaction_result_message', $message );
			$message = str_replace( '%purchase_id%', $report_id, $message );
			$message = str_replace( '%product_list%', $product_list, $message );
			$message = str_replace( '%total_tax%', $total_tax, $message );
			$message = str_replace( '%total_shipping%', $total_shipping_email, $message );
			$message = str_replace( '%total_price%', $total_price_email, $message );
			$message = str_replace( '%shop_name%', get_option( 'blogname' ), $message );
			$message = str_replace( '%find_us%', $purchase_log['find_us'], $message );

As I tried to solve my problem, I commented out some of these values and they still worked. So where else are these coming from? Modifying this file has no effect. This code doesn’t appear in 3.8.12.1 So where can I edit the email?
