Hey Noel,
I had a look at this.
To make it a bit easier (for me) to follow I pulled everything into one doc level function, which is called from all 6 buttons.
There is then one other doc level function used to initialize the doc level variables used in the counter.
It didn't look like you needed them to be global, but you can always put them back ...
Seems to work OK.
Let me know what you think.

2 functions are below and modifed PDF attached.
Cheers,
Jub

function DocVars()

{

    this.PlayButtonName = "Play";

    this.StopButtonName = "Stop";

    this.FirstButtonName = "First";

    this.LastButtonName = "Last";

    this.PrevButtonName = "Previous";

    this.FwdButtonName = "Forward";

    this.TheTarget = this.getField("Image");



    this.cnt = 0;

    this.bannerRunning = 1;

    this.bannerKey = 0;



    this.gIcons = new Array(4);

    gIcons[0] = this.getField('Image1').buttonGetIcon();

    gIcons[1] = this.getField('Image2').buttonGetIcon();

    gIcons[2] = this.getField('Image3').buttonGetIcon();

    gIcons[3] = this.getField('Image4').buttonGetIcon();

}

DocVars();

    // calling function straight away initializes everything



function Animation()

{

   var Location = event.target.name;

   switch (Location)

   {

   case PlayButtonName :

      bannerRunning = 1;

      bannerKey = app.setInterval("TheTarget.buttonSetIcon(gIcons[cnt++ % 4]);",1500);

      break;



   case StopButtonName :

      if (bannerRunning == 1)

      {

         app.clearInterval(bannerKey);

         cnt--;

         bannerRunning = 0;

      }

      break;



   case FirstButtonName :

      cnt = 0;

      TheTarget.buttonSetIcon(gIcons[0]);

      break;



   case LastButtonName :

      cnt = 3;

      TheTarget.buttonSetIcon(gIcons[gIcons.length-1]);

      break;



   case FwdButtonName :

      cnt = (cnt+1) % 4;

      TheTarget.buttonSetIcon(gIcons[cnt]);

      break;



   case PrevButtonName :

      if(cnt > 0)

      {

         cnt = (cnt-1) % 4;

         TheTarget.buttonSetIcon(gIcons[cnt]);

      }

      break;

   }

}
