After a caller entered the password (Enter Password Element), the system checks the input. If the input is "123", then the caller has entered the correct password and it is transitioned to element Protected Info,
where a secret message will be played to the caller. If the password entered is wrong, and the caller has made less then 3 attempts (n < 3), then it is transitioned to the Try Again Element.
The value of variable n is changed in the Try Again Element. Here, n is set to n + 1, which represents one more attempt for password. To set new value for a variable, select the element property sheet,
select the Action tab, then click the New... button.
If the caller has made more than 3 attempts on password, the system transitions to the Hang up element, where it simply disconnect the call.
The transition is defined in the element property sheet under the General tab.
