I'm using geometry nodes to generate different structures on a flat plane. Here's what it looks like right now:
As you can see, all the structures look the same. Each structure is defined by a group of geometry nodes which looks like this:
The plane itself uses geometry nodes that look like this:

I want to vary the height of each structure, but every time I use a random value, it comes out red.
I want to use a random value for each structure instance. How would I do that?
