Thank you for your reaction.
Basically yes. That would work for me.
But how to switch my list of cars to the "Date" list with SUMS of specific records of my choice?

You see, I'm able to filter how many machines I have sold in total, but I don't know how to make an "Avg. monthly sales" field that would divide the total sales by the number of months that passed by.

Yeah, we're going to need a table where each record represents a single month's sales for a single car, and the Interface would display the data from that table
