I'm pretty new to ModelBuilder and have been working on a tool that separates an exotic vegetation point feature class by species, then separates each species by treatment action, and then date.
I made a model using Iterate Field Values to create a new output feature class for each species in the input feature class. This portion worked great, but now I want to be able to go through each output feature class and iterate for another field value: treatment action. I have been researching nested models/integrating a model within a model but have not been successful. When I try to insert a new iterator, all the options are grayed out.
Here is a screenshot of the model that has worked so far and produced new feature classes for each species (taxon):
Is there any way to make the output values act as an input for the next iteration?
