Hi, i need to print total of sale order and invoice on the sale order report and invoice report in odoo 8 as a text

i have followed the instructions in this URl: https://www.odoo.com/forum/help-1/question/detailed-procedure-to-do-the-number-to-text-conversion-10504

But when i press "update" total link i get one character in this field. ( i start with sale order )

Any help will be appreciated 

Thanks
