The variable password_count is used to keep track of number
of password attempts. As we can see from the call flow diagram,
the Get Password element is the place where the password is
collected. If the password entered is not correct, the jump
element Password Incorrect sets the control back to Get
Password element. So every time the Get Password
element is executed (activated), we can increment the variable
Set Variable Value
The set variable value action is used
to update a variable value. An action is a set of activities the
system carries out for an IVR application.
To update the variable value, right click the Get Password
element, select Properties, then choose the Action
tab. Click the New button. From the Choose Action Type
window, select the Set Variable Value radio button. Click
From the Action: Set Variable Value window, select the variable
password_count, and set the value expression to be:
password_count + 1.
Actions are executed first when an element is activated. For this
action, it increments the password_count value to keep
track of the number of password attempts.
