The problem with "I learn best by example" is that when you copy and paste code from the internet without trying to understand it, you don't learn anything - as you have shown in your code sample.
That won't run, because neither
I'd suggest that as someone who "learns best by example" you go back to the place you got the code from, and look at the whole code: then try to learn how it works before you try using it as a basis for your own task.
While we are more than willing to help those that are stuck, that doesn't mean that we are here to do it all for you! We can't do all the work, you are either getting paid for this, or it's part of your grades and it wouldn't be at all fair for us to do it all for you.
So we need you to do the work, and we will help you when you get stuck. That doesn't mean we will give you a step by step solution you can hand in!
Start by explaining where you are at the moment, and what the next step in the process is. Then tell us what you have tried to get that next step working, and what happened when you did.
And to be honest, nobody learns best by example: you learn by doing, not looking. You can watch the Tour de France as much as you like, but that won't teach you to ride a bike yourself. Only sitting on a bike (with or without trainer wheels) and trying to ride will teach your body how to balance it and the subtle movements which you move to maintain that balance.
