Hai bisogno della funzione COUNTIFS() .
Quindi in questo caso:
=COUNTIFS («gun range», true, «Firearm», "Pistol")
Contabilità per delimitatori ; :
=COUNTIFS («gun range»; true; «Firearm»; "Pistol")
Dall'aiuto:
The COUNTIFS function returns the number of cells in one or more
collections that satisfy given conditions (one condition per
collection).
COUNTIFS(test-values, condition, test-values…, condition…)
test-values: A collection containing values to be tested. test-values can contain any value.
condition: An expression that can include comparison operators, constants, the ampersand concatenation operator, and references. The
contents of the condition must be such that the result of comparing
the condition to another value results in the boolean value of TRUE or
FALSE.
test-values…: Optionally include one or more additional collections containing values to be tested. Each test-values collection must be
followed immediately by a condition expression. This pattern of
test-values, condition can be repeated as many times as needed.
condition…: If an optional collection of test-values is included, an additional expression that results in a boolean TRUE or FALSE. There
must be one condition expression following each test-values
collection; therefore, this function will always have an odd number of
arguments.
Notes
Each value in test-values is compared to the corresponding condition.
If the corresponding values in each collection meet the corresponding
conditional tests, the count is increased by 1.
