francesca_ph, I don't know if anybody ever answered you on this but I was also trawling for the same instruction set and did not find it, so I'll write my own.
- Download the latest version zones_table_rate_for_multiple_zones_1-1.zip from the first page of this thread.
- Unzip the file maintaining the directory structure of the zip file:
i.e. \zonetable\includes\languages\english\modules\shipping\zonetable.php
and \zonetable\includes\modules\shipping\zonetable.php - Copy these files to the existing directory structure of your Zen Cart installation
i.e. webroot\includes\languages\english\modules\shipping
and webroot\includes\modules\shipping - In Zen Cart admin go to Modules -> Shipping and you should see the new Zones Table Rate option at the bottom of the modules list.
- Click on Zones Table Rate and in the right hand column it should give you a "+Install" button, click on this and the installation is complete

You can now configure the module as discussed in this thread!
