tax rate on invoice.tpl

I’m trying to figure out how I could see the tax rate instead of tax value on invoice.tpl, can you help?



example:



I have 3 different VAT rates: 4%, 10% and 20%



The invoice, will show the bought products this way:



prod.code - description - tax value - price

000123 - lorem - $9.09 - $100

000456 - dolorem - $16.67 - $100

000789 - ipsum - $3.85 - %100



but I would like to have it in this way instead:

000123 - lorem - 10% - $100

000456 - dolorem - 20% - $100

000789 - ipsum - 4% - %100



Any suggestion? I’m trying to replace {$oi.tax_value} with {$oi.tax_rate} but nothing will show up…



many thanks in advance

ok, I found the way myself, thanks anyway!
