Load Random Frame In Flash

I am inexperienced with flash.  I am trying to insert code into a flash file that will make the file load on a random frame each time the page is loaded.  I have read another similar post and have tried using the code provided, unsuccessfully.  I wonder if I put the code in the wrong place or there might be something I am missing.

This is a very simple time line with 4 keyframes.  I just need the file to randomly "go to and stop" on any of those frames when users load my the web page.
var arr = new Array(2, 3, 4, 5);
var rnd = Math.floor(Math.random()*arr.length);
 
gotoAndStop(arr[rnd]); // Or gotoAndStop, depending on what you want to do.

Your code is correct (using Actionscript 2 anyway).
I've just created a new file with it and it works fine.

Have you placed this on the timelime? i.e. selected frame 1 and added this to the Actions panel?

PS.

You can add trace commands to see what Flash is doing (whilst you are creating the file).

Amend your code like this:



var arr = new Array(2, 3, 4, 5);
trace("Array content: "+arr);
 
var rnd = Math.floor(Math.random()*arr.length);
trace("Array length: "+arr.length);
trace("Random Number: "+rnd);
 
gotoAndStop(arr[rnd]);
trace("Array number at random element: "+arr[rnd]);

Hello!  Thanks for your quick reply.  I inserted the code into the actionscript code for the first frame in the timeline.  When I put in the tracing code I got output like this:
Array content: 1,2,3,4
Array length: 4
Random Number: 2
Array number at random element:3
....
And it seems to work, some what. But every time I hit refresh the same frame comes up.  Only on every five or ten refreshes does another image comes up.  But it is usually only two frames, never the other two.  Any idea why this would happen?

I have attached a sample of the file, with a few random pictures thrown in on the slides.  So you can see how I have it setup and perhaps offer some suggestion?

No files attached?

Hit refresh?

Do you mean as you are viewing it in a browser window?

Sorry, yes I mean if you load the flash in a browser window and hit refresh.  Also, it does the same thing each time I do a publish preview within flash.  

Sorry, I guess it will not let you attach .fla files.  

I have attached the only code I have in my timeline.  Again, there are 4 frames.  This code is in the first frame.
var arr = new Array(1, 2, 3, 4);
trace("Array content: "+arr);
 
var rnd = Math.floor(Math.random()*arr.length);
trace("Array length: "+arr.length);
trace("Random Number: "+rnd);
 
gotoAndStop(arr[rnd]);
trace("Array number at random element:"+arr[rnd]);

If you change the filename from .fla to .txt you should be able to attach it.
