Another question regarding .toLowerCase().

In my code everything runs fine exept line 33 inside the last else statement. If I remove the .toLowerCase() the program runs fine. My question is, why is the .toLowerCase() method making the program not work? Want some insight on why this function seems a bit tricky? Thanks for your time!

You are also going to get an error since you are passing the integer index i into print instead of the object.

Since your object.name is capitalized the if statement is never executing. You need to call .toLowerCase() on both answer and object.name.
