error code in dax

Hi all, 

we have installed a lot of IoT devices in US and EU, I would like to check if 
minimum voltage of devices installed in US insider range: 5V -12V
minimum voltage of devices installed in EU insider range: 5V -9V

if above condition satisfied, then notification should return value 1,

the table visual as result will be like following:

IoT device ID Min VoltageRegionnotification
112211EU0
11338EU1
114515US0
115511US1

 

I have following code

MinVoltageN =
VAR _minV=min(datatable[VOLTAGE])

VAR _showminvoltage =
SWITCH( TRUE(),
VALUES(TRACKSHEET[REGION])="EU"&&_minV<9&&_minV>5,1,
VALUES(TRACKSHEET[REGION])="US"&&_minV<12&&_minV>5,1,
BLANK()
)

  -- Notification
VAR _Notificationminvol =
      if (_showminvoltage, 1,0)
    RETURN

 

I got following Error Message:
MdxScript(Model) (127, 1) Calculation error in measure 'Notification'[MinVoltageN]: A table of multiple values was supplied where a single value was expected.

 

appreciate your help and comment!

 

Thanks in advance!

    Try

    MinVoltageN =
IF (
    ISINSCOPE ( TRACKSHEET[REGION] ),
    VAR _minV =
        MIN ( datatable[VOLTAGE] )
    VAR _showminvoltage =
        SWITCH (
            TRUE (),
            VALUES ( TRACKSHEET[REGION] ) = "EU"
                && _minV < 9
                && _minV > 5, 1,
            VALUES ( TRACKSHEET[REGION] ) = "US"
                && _minV < 12
                && _minV > 5, 1,
            BLANK ()
        ) -- Notification
    VAR _Notificationminvol =
        IF ( _showminvoltage, 1, 0 )
    RETURN
        _Notificationminvol
)

        My guess is that the problem was triggered in the total line of a table or matrix value. If the region wasn't filtered down to a single value, as would be the case for a total, then VALUES will return all the regions as a table, and you can't compare a table with multiple rows with a scalar value. By checking ISINSCOPE you are guaranteeing that there will be only 1 value returned and so you can compare that to a scalar value.
