Close price of different dates not showing up in Explorer

[koushik.paul]

In the explorer, I am trying to display the Close price at 9:20 AM for a range of dates. However, the Close price being displayed is only the current date's price which is incorrect. Kindly help !!

CODE:

AddColumn(LastValue(ValueWhen(TimeNum() == 092000, Close,0)), "Close", 1.2);
