When you have a problem with your code don't be shy to post your code and the error you're getting so that you can be assisted by a moderator, helper, or any codecademy user that is capable of doing so.
But when you are satisfied with the help you have received and your code is working as it should it is very considerate and tactful to click the solution button below the reply that has helped you rectify and understand your code,
This is also a way for other helpers, or moderators to identify that a topic can now be closed.
Additional Note: If you really like an explanation or solution to your problem feel free to like it as well.
The solution button is the left most button below a reply to a topic that you have created.
In the event that you are still not satisfied enough to acknowledge a solution to your problem, don;'t hesitate to ask for clarification or a second explanation.
