wml variable

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

The following example will create a variable named i with a value of 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:





To use the variable we created in the example above:


You selected: $(schoolname)
