Adding sale tracking code for price comparison website

hi,all,

I have tried search a few threads and add the code myself in /home/igrabcom/public_html/includes/templates/mytheme/checkout_success/tpl_footer.php

but i have get no luck could any one help if i did it right or not? the code i added as below:

<img height=0 width=0 src="https://www.myshopping.com.au/sale.asp?mid=my_id&amount=<?php echo $order_summary['order_total']; ?

and here is what frank put in other thread:

https://www.zen-cart.com/showthread.php?148374-PPC-tracking-code-where-to-insert-in-Checkout-Success-page

can anyone help with this?

Well if this was all that was put in the file:

<img height=0 width=0 src="https://www.myshopping.com.au/sale.asp?mid=my_id&amount=<?php echo $order_summary['order_total']; ? 

Then it is incomplete and therefore likely not to work either.

<img height=0 width=0 src="https://www.myshopping.com.au/sale.asp?mid=my_id&amount=<?php echo $order_summary['order_total']; ?>" /> 

May need more info if that doesn't work. Looks right, but let it set in a second.
