Answer 1

MONTH(Date) is not a column you SELECTed, so it can't appear in your HAVING clause.

If you meant to only SUM the Bills from rows where the month is between 1 and 3, then that is a WHERE clause, not a HAVING clause.

If all the rows in each PCI group have the same MONTH(Date), then you can add MONTH(Date) to your SELECT clause in order to use it in the HAVING clause.
