Jmeter - how to register several users in the system using CSV Data Set Confi?

Question

A/b testing

Good day,
Can anyone come across help.
Working with the Jmeter tool, I want to create the maximum load on the site. There is a script and all parameters are set.

This is what I wrote in the request that is responsible for logging in:

Like this is displayed in the report after the login failed, that is, you can see what request is sent:

Thank you.
