Tax not showing in invoice.php

[kelvyn]

I have loaded all the products with their tax-inclusive price. I have made a tax zone and put the shop in it (as mentioned at: http://guide.oscdox.com/osCommerce_A...axes_Setup.htm )

It all works OK, but when I come to print the invoice, it shows the tax as being 0.00% and the tax exclusive price as being the same as the inclusive price.

I've read lots of forum postings on TAX, but none seem to solve my problem. I'd even settle for "fudging" the page just to subtract the vat from the total for the "exclusive" column to display in the "exclusive" column. There is no need for me to show or upload vat (tax) -exclusive prices. Is there any way round this?

1 x Product   S122B 0.00% £29.00 £29.00 £29.00 £29.00
