    It's my pleasure!

    You can create another calculated column.

    Last month value =
MAXX (
    FILTER (
        'Table',
        'Table'[Record ID] = EARLIER ( 'Table'[Record ID] )
            && MONTH ( 'Table'[Month] )
                = MONTH ( EARLIER ( 'Table'[Month] ) ) - 1
    ),
    'Table'[Value]
)

    Result:

    I attach my sample below for your reference.
