COLLECT and ISBLANK
Hello community,
I have a sheet called Boundary.
ColumnA is called "Distance" and has integers .
ColumnB is called "distance_to_increment" and has either an integer or a blank field.
From another sheet called Summry, I would like to sum, all distances which have a blank field for column B.
I struggle with the formula, for the "is blank" part.
SUM(COLLECT({Boundary:ColumnA},{Boundary:ColumnB},"")) does not work.
It seems "" does not refer to a blank field. How could I use ISBLANK() or something else ?
Thanks.

Replace "" with ISBLANK(@cell).
