How do I respond to someone after I asked question

[JusticeforLt.Col.Sutton.]

I asked a question.  Then people submitted a post.  How do I respond to the person trying to help me. For example, I asked a question, Berta responded .  How do I respond to each post.  Thank you so much in advance.

After a post is made in the thread or new thread. Scroll down until you see  "answer this question" its usually a inch or two below a post. Then click on that with your mouse and you can start typing your response.  A lot of software/websites is now going to "tablet view" instead of staying with "desktop view."

Okay.  Here goes my first response and thank you.
