Setting Google ecommerce tracking HELP

Hello, Im new to the ecart stuff. I have it working good on my site and would like to add the google ecommerce tracking. I already have google analytics started but I just not sure what and where to put the snippets of code google says to add. Is there step by step instructions anywhere. I was looking and can't find. I found a few quesitons with answers on the forum but I need a step by step guide.

Thanks in advance, sam

No, we do not have a step by step guide, it takes custom coding to add the google eCommerce analytics, if you need assistance adding this, we can help in a premiere support appointment.

This is so dissapointing. I did searches and many of the other carts out there give step buy step guides and vidoes on how to do. I watched and could easily follow. I do not plan on paying to get help that should be provided in support of your software. This is not the only time that there is little support on topics with your ecart. I do know in the future I will look at other software that provides more support and information on there software. Much of the support give is not in detail. I just want to express disappointment.

Sincerely, Sam Barnhart
