A WML code includes a header and a body. As you can see, the header specifies two links and the WML version as well as that of XML, on which WML is based. You'll often read and hear about a WML deck - the metaphor used for WML code is a deck of cards.
User agents are capable of displaying and navigating between cards.
The title is displayed on the user agent's screen. When you show a card in the user agent's display, it will show all strings and input fields defined in the WML card. Look carefully and find all strings that are not part of any wml tag. Use the up and down arrow keys to navigate to hidden parts of the card. Notice the header of the card, Currency.
