Thanks for your prompt reply. Didn’t realize there was an expression forum… will post there next time.

What I want to do is to increment the y position for each layer and then decrease it again.

Using position+[0,(index-1)*1000] the first layer starts from 0, 2nd 1000, up to the 50th which is 49000. Now I want the 50 layers after this to decrease from 49000 back to 0. i.e. 51 y position at 48000, 52nd at 47000 and so forth.

I hope I manage to explain properly..
