Los parámetros PeriodTypeSel, PeriodDaySel y PeriodMonthSel se interpolan sin procesar en fragmentos de igualdad y comparación de funciones entre comillas simples, y las ranuras de filtro más los identificadores de Línea y Columna se interpolan de manera similar sin lista blanca y sin enlace de marcador de posición.
