WML Variables

Variables
When a user switches from card to card in a deck, we need to store data in variables. WML variables are case sensitive.
Specify a Variable with the Setvar Command
When someone executes a task (like go, prev, and refresh), the setvar element can be used to set a variable with a specified value.
The following example will create a variable named i with a value of 500:
<setvar name="i" value="500"/>
The name and value attributes are required.
Specify a Variable through an Input Element
Variables can also be set through an input element (like input, select, option, etc.).
The following example will create a variable named schoolname:
<card id="card1"><select name="schoolname"><option value="HTML">HTML Tutorial</option><option value="XML">XML Tutorial</option></select></card>
To use the variable we created in the example above:
<card id="card2"><p>You selected: $(schoolname)</p></card>

WML Examples
A WML deck with two cards - one for user input and one for displaying the result - can be set up, as demonstrated in this example:
<?xml version="1.0"?><!DOCTYPE wml PUBLIC "-//WAPFORUM//DTD WML 1.1//EN""You are not allowed to view links.
Register or Login"><wml><card id="card1" title="Tutorial"><do type="accept" label="Answer">  <go href="#card2"/></do><p><select name="name">   <option value="HTML">HTML Tutorial</option>  <option value="XML">XML Tutorial</option>  <option value="WAP">WAP Tutorial</option></select></p></card><card id="card2" title="Answer"><p>You selected: $(name)</p></card></wml>
