Ok, love the mod.
One change that I made. I currently do not have a Fax for my business, so there is no reason for me to have an empty fax on my invoice.
I changed line 89-90 on super_invoice.php to this.
<td class="invoiceHeading" align="left" valign="top"><?php if (STORE_FAX != ''){echo HEADER_FAX;} ?></td>
<td class="invoiceHeading" align="left" valign="top"><?php if (STORE_FAX != ''){echo STORE_FAX;} ?></td>
so that if down the road I add a fax, and fill the info in the admin, that the information will then automatically show on my invoices, but for now, it doesnt.
