Add numbers to ranges

hello everyone, I try to enter numbers in each of the ranges to which they belong, but I still do not get the expected result.
I need your help. Thank you.

You want to make sure you’re checking the upper and lower bounds individually and that they’re both true, not just equal (although in this case you wouldn’t ever have both conditions failing unless your bounds were the same). You also need to make sure you have an equal number of items as lists being added to.
