Tell us what’s happening:

I’ve made everything as needed but any of tests (17-24) is not passed, even the title. and i don’t actually understand what i should to do in my browser console (all what i see in there is adblocker errors)

Your code so far

First, it sounds like you should disable your adblocker and probably any other extensions which might be interfering.

class named create_spend_chart(categories) that returns a bar-chart string

Your function prints a lot of things but it does not return anything.

3

so the function should return whole result (table) at ones?
And one more question: is it important what functions should return the result, not print?

4

Yes, exactly.

It depends what the instructions say. Usually they should return something but the instructions will tell you exactly what the functions require.
