Hello! I am abit confused, how does one add days to the invoice date template. As in invoices must be payed within 10 days. so say the invoice date is 1/2/2014 but i want to add a field to show the last date of payment which is 10 days from the invoice date..
date code in the .odt is : <if test="invoice.invoice_date"><formatLang(invoice.invoice_date, invoice.party.lang)>
