Let me know if you need more help please.
I have already done that. This is working now. However there a quite a few other problems with the slider. Autoplay doesn't work with YouTube Videos. But thank you
About autoplay, if you are using videos with audio, Chrome doesn't allow autoplay.
Video should be muted or requiere the action of the user to start playing.
