Let's arrange the fields
The program will show the order tab in editing mode. Our goal is to bring the Date and Customers fields to the first screen. Select the Detail page and click the pencil button inside the Date field. Once the menu is open, select the Panel item that will allow you to move the field between the various pages of the tab and then select the top Detail.
In the next chapter, we will start entering the calculations to give a value to our order.
