Roundup not summing correctly

Hi,

I am using the following measure to round up, however it is not summing correctly its just rounding the total. I found where someone wrote to use the following measure below, however this is on a column not a measure and my below measure will not populate where they have 'Crate EQ'. Any ideas?

Round_new =
VAR _new =
    SUMMARIZE ( 'Table', 'Table'[Crate EQ], "_value", [_your roundup] )
RETURN
    IF (
        HASONEVALUE ( 'Table'[Crate EQ] ),
        [_your roundup],
        SUMX ( _new, [_value] )
    )
