I am trying to do the same, but when I enter "AddDays(Curredate(), -90)" is not accepted

Hi Gonzalo,

You have a typo there. its CurrDate() and not "Curredate()".

Is that the problem or was just writing it here on the forum?

Regards,
João Rosado

I have the same issue and the error "Unexpected ',' in expression"

Any idea?

show your expression Patrick.

Patrick, please, show your expression, but in a new topic.
Let's not wake the dead ;)
