Hi, I just installed the Simple Google Analytics Mod on my website for the first ime, which is running Zen Cart v1.3.9h. But I'm having a bit of trouble with the customization steps that are listed in the Readme file. In Step 3, Part B where it instructs to insert the given code into the /includes/templates/[your_template]/common/html_header.php directory of the website, I've run into the issue of my site not having a html_header.php file. I'm running the cherry zen template on my site and am wondering how I should proceed with the install from here on? Thanks in advance for any advice anyone can offer.
