Hello, everyone! I'm sorry if this seems off-topic, but no one responded to my original post about it and I'm hoping it's an easy answer that one of you knows!

I am signed up for Yahoo Search Marketing rather than Google. In order to set up simple analytics, I am supposed to "Copy the HTML code below and insert it between the <HEAD> and </HEAD> tags on your site's conversion page(s)." The code begins "<SCRIPT language="JavaScript" type="text/javascript">...

>> Where is this code supposed to go? <<

Do I add an html header to define_checkout_success.php and put it in there? I am very, very basic with coding, so any help you could give would be appreciated!

Thanks so much!
