If you give us a runnable code snippet less than 20 lines, we can give you a better answer, but in general what I can say is that if you use brackets twice, that you have a collection inside of a collection (like a matrix, if you're familiar with those from math; no worries if not). The first bracket accesses the inner collection, and the second bracket accesses the item inside that collection. A string can be thought of as a collection of characters, so if you had a list of strings you could access the third character of the second string with
