Yeah, %= does the same I believe.
Im a bit too very-old-school to use the =operators "naturally".
I do that sort of thing at 'clean up and document code' time

Let keep at it anyway. The sample you posted in your initial post is
your 'walk'ing animation, can you post the code thats around the code
that handles your 'stand' animation instead? And do you use the templates?
And are you using lite-c or c-script?
