play videos and mousepressed

Hi, i am recently doing some work using processing and arduino. i am new.. so it might be basic question. there are totally 7 videos. and two separate arrays(or playlist)? list1>videos 1, 2, 3, 4 list2> videos 5,6,7

so when it starts, list1 will be played, (1-4) and if you press the mouse, current video will stop and playlist 2 videos randomly (5~7). and after the video ends, it returns to play list1.

this code is working to playing list 1 and if i press the mouse, the movie stops for a sec and play again. not going to play list 2...

TT...
