"Be barking up the wrong tree" is an idiom that means you are pursuing a wrong course of action or misdirected in your efforts. This expression is used when someone is trying to achieve something, but their approach or efforts are unlikely to succeed. For example, if you ask your friend for advice on a specific topic, and they give you incorrect information, you might say, "Sorry, I think you're barking up the wrong tree, but thanks for trying to help me." It means that they are not providing the right advice, or they are not the right person to seek help from.
