Arguments:

The argument of this function may contain inter-record functions which in themselves return a list of values.

Example with expression:

RangeMissingCount (Above(MinString(MyField),0,3))

Returns the number of non-numeric values in the three results of the MinString(MyField) function evaluated on the current row and two rows above the current row.

Disable sorting of MyField to ensure that example works as expected.

MyField	RangeMissingCount(Above(MinString(MyField),0,3))	Explanation
10	2	Returns 2 because there are no rows above this row so 2 of the 3 values are missing.
abc	2	Returns 2 because there is only 1 row above the current row and the current row is non-numeric ('abc').
8	1	Returns 1 because 1 of the 3 rows includes a non-numeric ('abc').
def	2	Returns 2 because 2 of the 3 rows include non-numeric values ('def' and 'abc').
