javascript fix

Need to fix some short code: On click of any video: - video array starts playing from that clicked video. - Videos play at ended one after the other automatically. - What is not working: . user should not be able to click on button for (currently playing) video. . right now, user can, and with each click array increments and video play not in order. Need somebody to fix this, in the next couple of days. Very simple if you are an experienced programmer. It is for an ipad application, no need for other browsers. Using jQuery. CSS3/HTML5. I am attaching files, without the videos due to size.
