I have a field where I'd like to count the number of instances the field has the max number for that given column. For example, if the max value for a given column is 20, I want to know how many 20's are in that column. I've tried the following formula but I have received a "Cannot mix aggregate and non-aggregate arguments with this function."
IF [Field1] = MAX([Field1])
THEN 1
ELSE 0
END
