Repeat calculation on automatically created planes

Hi
I have a point cloud and along the point cloud I create planes which I divide into cells and later use them to calculate the density of the points projected on the planes within the cells. So far so good. Now I have the problem that I can’t get it to calculate this for the individual planes. At the moment the result is projected from the first planes to all of them. Can anyone help me how to do this for each individual plane individually?

Can you post the file?
