Fix Jquery / Javascript Type Issue

I have give some freelancer (freelancer.com/u/pmurugan) my script to work on it and he totally mess-up my script! I have re-uploaded my backup from my pc, but since there one important function was stop working, because i don't know how and why. Normally it is auto-watching youtube videos from database after member login, but when timeout for first video is over, next video doesn't load. So I need fix first of all this issue what was nicely working before that freelancer touch my cpanel script! Thanks for BID PS: I DO NOT answer on soem new freelancers and I prefer some company not some "kids" who play here on freelancer and loosing my time. If you want long-term projects made good job and you get paid.
