Revert to default scale when seed changed? So this is the problem. This is the node network I have (simplified). it just takes random list from objects and should change the scale to zero when value is animated. It works but, for instance if the animated scale gets to 0 and after that I want to change the seed of the random selection, those scaled down do not go back to scale 1, but stay scaled down, thus the effect is added. Any clue how to get them back to initial scale? Thanx in advance.
Your approach doesn't explicitly set the scale of all objects, some of which might have been scaled to zero at some point, so their scale never reset.

To fix that, generate a list that define the state of each object, then use that list to control the scale of objects in whichever way you want. It is clear to me that you want to control how many objects gets scaled to zero, so to implement that, we are going to generate a list that has a certain number of zeros, with ones for the rest of the list, such list can be generated using the Fill List node. To make sure it is randomized, we can shuffle it or shuffle the object list itself as follows:
