if date not selected add todays date

[Anonymous]

Hi,

I cant seem to find the syntax error in the formula below but i would also like to add "If this is not populated I want the date to chose the current date".

how can I add this to the following syntax please.

So if the 'AsAtDate' is populated the date is taken from this but if left empty the data is taken from today.

SUM( {$<%Date<={AsAtDate}, RecordType= {'WebTraffic'}, Area= {'SR'} >} Sessions )
