Calculation function only returning minutes

[morther]

I have created a New Column called Downtime.  It is supposed to take the total Downtime Minutes and break it into Days, Hours, and Minutes.  It is pulling the remainder minutes properly but is not adding the hours beforehand.

(Source Column)
Downtime Minutes                                         Downtime
99.00                                                                     0 day  00 hours  33 Min

This should read 0 day  01 hours  33 Min, but is missing the hour.

Below is the DAX code:

Downtime =
VAR dayNo =
    INT ( EventLogDetail[DowntimeMinutes] / 1440 )
VAR hourNo =
    INT ( MOD ( EventLogDetail[DowntimeMinutes], 1440 ) / 60 )
VAR minuteNo =
    MOD ( MOD ( EventLogDetail[DowntimeMinutes], 1440 ), 60 )
RETURN
    dayNo & " day  "
        & FORMAT ( hourNo, "#00" )
        & "  hours "
        & FORMAT ( minuteNo, "#00" )
        & " Min"

Any help would be greatly appreciated.

Thanks,

Mike
