Adding Fax Number Field to Packing/Invoice

[esugrue]

So is there an easy way to `call the field from the customers table' so that it will display/print on the invoice and packing slip.

You might make your own function that can call the customers and customers_info tables similar to the function zen_products_lookup in the functions_lookups.php and retrieve the contents of any field you like ...

Makes it a little more useful than a single function for just 1 peice of information ...

So for somone who doesn't write pages of code for a living, that would be a no, since unless you can understand how all those function calls and lookups etc are coded and work together, it's not easy.
