Same Height Bric

I’m using Blocs 3, trying to use the ‘Same Height’ bric.

I’ve followed the instructions from the video on this page: https://www.bricsdesign.com/sameheight.html

Doesn’t seem to be working. The only thing I can think of is that this doesn’t work on Blocs 3? Or I am somehow doing something wrong even though the directions are pretty clear.

Any help would be greatly appreciated. :slight_smile:
