Filter a Report based on a date

Filter a Report based on a date

Hi,

I am building a club membership app.
Each member has an expiry date.
I would like to generate a report that displays a list of anyone expiring within, say, 45 days.
On a the report, I am trying to use a Criteria condition.
Expiry Date >> Before >> (now + 45 days)

How do I code the "now/today + 45 days"?

Best regards,
