How do I change layer scale for several layers at once?

I have 12 layers that need to scaled at once, is there a way to do them all at once instead of going each one at the time?

If they are consecutive, or named like MyLayer1, MyLayer2, MyLayer3..., you can do this in a loop.

For "n"=1 to 12 : Set layer "MyLayer"&loopindex scale to 2

great thanks i will try it.
