They purposely mislead you sometimes, because in the real world sometimes the bugs are silly mistakes.

Ok. So strings are immutable. That just means they can never be changed, ever. If you want to change a string, you have to rewrite it.

There are ways to split the text, change a letter, and recreate a string. But for now they just want you to change it manually.

Any questions you have just post them. I lurk here pretty often and will usually answer fairly quickly. Welcome to the wacky world of coding!
