Misty, thanks for the link to the mod.
I tried installing the module. I am new to Zen cart and I think I messed up something. :oops:
I followed the given instructions, stated in the "readme.html" file in the package.
Prepare the package for upload to your server by renaming the following folders to match your template name: includes/modules/YOUR_TEMPLATE and includes/templates/YOUR_TEMPLATE.
If you are installing onto a new install or upgrade of Zen Cart 1.3.5 or later then with most good FTP programs (such as FileZilla) you can simply drag and drop the admin and includes directories into the root directory of your site. The files are already arranged in their directory structure.
There are six core Zen Cart files modified by this add-on. If you have installed other add-ons or customised your cart since your Zen Cart installation or upgrade, you will need to check whether they have changed any of the following files:
admin/includes/stylesheet.css
admin/orders.php
includes/classes/order.php
includes/functions/functions_lookups.php
includes/modules/pages/checkout_shipping/header_php.php
includes/modules/pages/shopping_cart/header_php.php
In addition, one file is over-ridden
includes/templates/template_default/templates/tpl_shopping_cart_default.php
So far, I have been able to set the quantities as per the attributes. The user is also warned if a particular attribute product is out of stock. The user can place an order. However, in the admin section I cannot veiw the orders.
If gives me the following error when I click on "customers -> orders"
Fatal error: Call to undefined function zen_get_orders_comments() in /home/.elvine/shop2/shop2.ajayenterprise.com/admin/orders.php on line 807
I am also attaching the screen shot of the error I am getting.

I have tried to copy all the files twice to the server to make sure that I have not missed any. But I think I have missed some file. I would highly appreciate if any one could help me figure the file I have messed up while coping.
Thanks for the help in advance.
