  Sample input:
OmitValues ( 2 "¶" 3 "¶"4 "¶" 5 "¶";3 "¶" 5 "¶")
  Sample output:
2 "¶" 4 "¶"

  Function definition: (Copy & paste into FileMaker's Edit Custom Function window)

Opposite of the built-in "FilterValues" function. Will return values from the left-hand parameter, "values", that are not in the right-hand parameter, "omitList". Both parameters are value lists.

Scrambled output caused by empty values in omitlist has been fixed.

I have noted that the last value of the values parameter will not be evaluated correctly without a trailing paragraph return (¶), if that value is within the omitList. Following is a suggested revision, which adds the paragraph return character (¶) to the values parameter result via a var=expression parameter in the Let function:

Let ( [ values = values & "¶" ; x = RightValues ( omitList ; 1 ) ] ;

If ( x = "¶" ; OmitValues ( values ; LeftValues ( omitList ; ValueCount ( omitList ) -1 ) ) ;

If ( ValueCount ( omitList ) > 1 ;

OmitValues ( Substitute ( values ; x ; "" ) ; LeftValues ( omitList ; ValueCount ( omitList ) -1 ) ) ;

Substitute ( values ; x ; "" )

) ) )
