COUNTA if blank

[AA622]

Hello

I am using COUNTA to count whenever there isnt a date in a row and then i put it in a card to showcase count.

DOScountbypurchase = COUNTA(Table[Dateofpurchase])

When I select a value where there is no date of purchase it shows "blank" in the card.(see below)

How do I showcase a custom message whether it be "0" or "No Dates" instead of saying "(Blank)".

Hi,

Drag this measure to a card visual

Measure = coalesce([DOSCountbypurchase],0)

Hope this helps.

@AA622 

you can try this

DOScountbypurchase = COUNTA(Table[Dateofpurchase]) +0

or 

DOScountbypurchase =if(isblank( COUNTA(Table[Dateofpurchase])),"No Dates")
