Hello everyone,
I'm trying to get a average of a column if the cells in another column are within 90 days of today.
My current formula is =AVERAGEIF([Pick-up Variance]:[Pick-up Variance], [Pick-up Date]@row>TODAY(-90)).
I tried using AVG(Collect) as well with no luck.
=AVG(COLLECT([Pick-up Variance]:[Pick-up Variance], [Pick-up Date]:[Pick-up Date], , but I'm getting a Invalid Operation.'
