This is a user-to-user forum, not a chat service. There is no way you should expect a response from a fellow user in under 1 minute. First someone has to see your post, then figure out what you are actually asking (and it isn’t obvious from what you posted) and finally think they can help. That can be minutes, hours, or even days later. Fortunately, you got one answer that may be a response to what you asked. Or may not be. And it was only a little over an hour later - on a US national holiday.
