Can you tell me how to get the account.tax field name in my invoice report? I have created a new row between description and quantity and i want to have just the field account.tax name there for every article.

With the [[ a['type']=='article' and ('/ (' + a['tax_types'] + ')' ) ]] i get "19% Umsatzsteuer" but thats more that i want i just want to have 19%.

Can anyone provide me the bracket for that?
