  1. Launch Flash Designer and choose Blank
  2. Set movie dimensions 230 x 100 (or any desired) with Frame > Frame Size
  3. Change frame delay to “0.05″.
  4. Choose “Frame” > “ActionScript” and paste the code: 
    // generate random number (f) but different than the last one (l)
// the number will be between 1 and 6

while(f==l) { f = Math.Floor(Math.Random()*6)+1; }

// remember the last random number
l = f;

// jump to a frame
if(f==1) gotoAndPlay("Frame 2");
if(f==2) gotoAndPlay("Frame 3");
if(f==3) gotoAndPlay("Frame 4");
if(f==4) gotoAndPlay("Frame 5");
if(f==5) gotoAndPlay("Frame 6");
if(f==6) gotoAndPlay("Frame 7");
  5. Choose “Frame” > “Insert”, put Qty: 6 and delay 2 seconds
  6. Put graphics on each frame (from Frame 2 to Frame 7) for example numbers
  7. Hit F9 for preview.

    This example has been the best match for what I am trying to accomplish in a banner ad I am working on! I ran into one problem with my test file:

    - I am using Flash CS5 with AS2.
    - everything in my test file went smoothly except the random order did not work (my frame sequence ran 1,2,3,4,5,6,7, repeating)
    - the AS compiler error I received was:
    Scene=Scene 1, layer=actions, frame=1, Line 4 There is no method with the name ‘Floor’.
    - I also tried recreating the test file using AS3, but encountered more compiler errors =(
    - here is the (same as above) code I copied & pasted:

    // generate random number (f) but different than the last one (l)
    // the number will be between 1 and 6

    while(f==l) { f = Math.Floor(Math.Random()*6)+1; }

    // remember the last random number
    l = f;

    // jump to a frame
    if(f==1) gotoAndPlay(“Frame 2″);
    if(f==2) gotoAndPlay(“Frame 3″);
    if(f==3) gotoAndPlay(“Frame 4″);
    if(f==4) gotoAndPlay(“Frame 5″);
    if(f==5) gotoAndPlay(“Frame 6″);
    if(f==6) gotoAndPlay(“Frame 7″);

    If there is anything I did wrong or any changes I need to make, please advise. Thanks!!!

    P.S.
    The compiler error went away after changing 2 upper case letters (Math.Floor and Math.Random) to lower case Math.floor and Math.random.

    Unfortunately my frame sequence is still the same (rather than random).
