Enter the default quantity or select a value from the drop-down menu.
To customize the period, click on the Custom button, check the month and year and click Set Months.
Click Ok to close the window.
To remove a saved setting, click on the contract, and uncheck the boxes and click Ok.
Or, click on Cancel to close the window.
