How to make COUNTIF based on adjacent column condition?

Question

Google Sheets

Good afternoon!
I made a questionnaire, got the results, now I want to play a little with the data, build charts, graphs, and so on.
The standard Summary does not suit me.
I want to know which factor is the most determining for the owner of a specific application

. Tobish, I want to summarize column J by the value "Cost of the trip", provided that, in column I, the value is "Yandex.Taxi"
I wrote such a formula, but it gives strange numbers
=IF (' Form Responses 1'!I:I = "Yandex.Taxi", COUNTIF('Form Responses 1'!J:J, "Travel cost"), "Error")
Is it even possible to perform such an operation in Google Doc? I really don’t want to go to Excel, but such an operation would be very useful in the future.

Answer 1

Most likely you need the formula COUNTIFS()
For example,

=COUNTIFS(A2:A9,"=Яндекс.Такси",B2:B9,"=Стоимость")
