Parameter does not work by adding to a date

[Syndicate_Admin]

Good morning.

I need to know why this DOES work:

CALCULATE(

[ven01_importe],

DATESINPERIOD(

dCalendario[Date],

NOW()-90,

90,

DAY

)

)

... And yet, this does NOT work:

CALCULATE(

[ven01_importe],

DATESINPERIOD(

dCalendario[Date],

NOW()-[Valor parMesesClientesPerdidos],

[ParMesesClientsPerded Value],

DAY

)

)

... taking into account that the measure [Value parMesesClientesPerded] returns the integer Nº = 90 (checked on a card) and taking into account that it is the result of a PARAMETER. The [Value parMesesPerdents] measure is:

Value parMesesClientsPerded =SELECTEDVALUE('parMesesClientsPerdidos'[parMesesClientesPerdidos])

It only works if the NOW() date subtracts an integer directly, by variable or by a measure, but it DOES NOT WORK if the integer number 90 comes from a PARAMETER.

Would anyone know how to tell me why?

Thank you very much in advance.

Best regards
