Jittering In-Out During Timelapse

Here is a time lapse I just created with my A480. I've created time lapses before but never seen this effect of jittering in-out all the time.

I'm using the following script which sets the focus at the start and keeps it fixed. This has always worked for me before. Any ideas what is causing this and how it can be avoided?

Note that the camera was on a secure mount inside a building and not moving.

thanks, Andy

Solved - the script used to work fine but now doesn't - it focuses for every shot. Strange as I haven't touch it since putting it on the camera over a year ago.
