I could say that you shouldn't be using sequences like I and many others have recomended in the past. However, if you insist on using them, then I'm assuming you don't want a tunnel outside of the sequence but want to pass a value to some other sequence. If that's the case, right click on the sequence structure where you want to pass the value and select "Add sequence local". You wire you value to it and can pass it to any subsequent frame.
