It's great that you want to help. However, posting answers that have already been given doesn't add anything to the thread except noise.

I recommend that you change your default sort order to "oldest" by clicking on your Avatar in the upper left. Click on Preferences, scroll toward the bottom of the page and select "oldest" as your default sort order. That will allow you to see posts in the order in which they were posted. Especially in threads this short, review the answers already provided to make sure you're not duplicating things.

Okay! Thanks for the Tip
