Start one one of 7 different frames

[JimH16]

I used this in a previous movie and now it won't work:
"
random_start = (random(7))+1;

if (random_start==1){
gotoAndPlay(5);
}
else if (random_start==2){
gotoAndPlay(10);
}
else if (random_start==3){
gotoAndPlay(15);
}
else if (random_start==4){
gotoAndPlay(20);
}
else if (random_start==5){
gotoAndPlay(25);
}
else if (random_start==6){
gotoAndPlay(30);
}
else if (random_start==7){
gotoAndPlay(35);
}
"

Basically I want the movie to start at one of the 7 points randomly each time. Any ideas where I'm going wrong?

Thanks

random was deprecated since Flash Player 5.
try using Math.random().

random_start = Math.round(Math.random()*7)+1; 

or a different approach -

stop();
arr = [5,10,15,20,25,30,35]; // frame numbers
arr.sort(function(){return Math.floor(Math.random()*3)-1}); // randomise the array
frame = arr[6]; // last element in arr
gotoAndStop(frame);

Thank you!
I adapted it to this:

stop();
arr = [2,30,60,90,120,150]; // frame numbers
arr.sort(function(){return Math.floor(Math.random()*3)-1}); // randomise the array
frame = arr[5]; // last element in arr
gotoAndPlay(frame);

But it never goes to frame 2. Is something wrong?

So strange I did the whole thing form scratch with your code. - It's like some of my pictures make it go wrong - it goes to 35 every time. It worked at first, then when I imported pictures the randomiser stopped working. really odd.
