Hi! Is there a ISDATE native formula in excel? I am trying to enter a formula in one cell (cell Z11) in which, it will display TRUE if T11 finds the same value or date in cells B11:R32. Please take note that I formatted cells T11 and B11:R32 as [$-409]d;@ so that it would only display as number of day (ex: 05 March, 2013 will display as 05).
Kindly help. Thank you very much in advance!
