Changing date to variable in set analysis

[gilldilpreet]

Hi,

I am trying to change the dates in the expression below to variables i.e. today() and today()-1 and today()-2 etc.

I have tried using the expression underlined in red but this doesn't seem to be working. 

Could someone advise please? 

Thanks 

Dilpreet
