You didn't tell us what you actually did, and especially which bits you think might be a mistake, so it's very difficult for us to answer this question. For example, you might have hit them with a hammer, or connected them to the wrong voltages, or washed them in a bath, or who knows what? Or you might have plugged them in correctly but used some sequence of commands that has caused a problem. But until you tell us what you did, we can't know which bit was wrong! > Thank you. > > Regards, > Sophie
