WML TAG:  refresh
<refresh> ... </refresh>
 
The refresh tag is used to update the current display. In other words, whatever card is currently being displayed will be refreshed.
 
This is referred to as a refresh task. A task is performed in response to an event. There are four tasks in WML: go, noop, prev, and refresh.
 
The refresh tag can only be nested inside an anchor, do, or onevent element. This tag can contain one or more setvar elements which are used to set new values for named variables.
 
Nested Tags:  setvar
 
Attributes
 
class
The optional class core attribute is used to assign one or more classes to the element. Multiple classes are separated by white space. The class name is case sensitive (i.e., Stocks and stocks are not the same).
 
id
The optional id core attribute is used to assign a unique name to a tag. The name must be unique to the entire deck and not just unique to a card. The first character of the name can be a letter or the underscore. The remaining characters can be any combination of letters, numbers, or underscores.
 
In this example, after the refresh anchor link is clicked, the variable named MyNumber changes from 71 to 348. In card2 the MyNumber variable is displayed using the dollar sign $ variable naming convention.
