why the expression # to insert data isn't works god

hello zoho i have a one question, in zoho crm when i go to make a one template for a sales order, budget, purchase order or any template in the inventory space,i use ${Órdenes de venta.Descuento individual} for example but i don't have any data in the moment i go to print . But when i use the product table this expression works. I must comment i use the spanish version.
