Welcome to the Get Help category!
This is where you can ask questions about your code. Some important things to remember when posting in this category 
- Learn how to ask a good question and get a good answer!
- Remember to include a link to the exercise you need help with!
- If someone answers your question, please mark their response as a solution
- Once you understand a new concept, come back and try to help someone else!
