I am having some troubles trying to create an invoice in Zoho CRM. I have defined a tax rate (VAT) with a value of 18%, and a product (Product A). Product A has VAT activated. When I create an invoice:

- If I click Tax on the product line, I get a message "No taxes associated to this product".

- If I click Tax at the bottom of the invoice, a box shows up which does include "VAT: 18%", but it behaves as it if the subtotal was 0 (which it's not).

Is this an error of Zoho, or am I doing something wrong?

Regards
