You can give a try with the layer.index.

thisComp.layer(1).transform.scale;

I guess you defined :

layer.name=« toto »;

So use thisComp.layer(« toto »).property(« ADBE transform » ).property(«ADBE Scale »).setValue(1).

(I think it’s better to use the proper names in case you share your script to a non-English person.)

Anyway, reading your post, I just want to have a precision : do you try to catch layers inside a precomp ?

 

Cheers,
