What do I do next after setting an entity price to a currency format?

Hello everyone who's reading my question, I'm a fresh developer at OutSystems and I've come across something that is hindering my project. 

In a nutshell, I'm creating a web application for my dad's job, a customer and order app manager.  I want to set the price of the order to a currency format, displaying things like "R$"(my currency symbol), decimal separators and so on, what do I need to do after setting the entity type to format? I need someone who is patient to help me step-by-step, since I'm a beginner
