Nop Emporium Sale of the Day Plugin

When enabling the sale of the day, there is a check box in settings as 'Show Special Price Countdown Timer'. When selecting it nothings happens.
Can anyone tell me where should i give the special prices and bring this countdown timer in sale of the day.

Update the product and add a new tier price with a quantity of 1, set the price to the sale price and add an end date.  The start date is optional.  Also set the Old Price.
