To debug the model, first REMIX and rename it, and then solve the challenges in order. Hit Run Code and test your model at each step.
Problems:
1. Nothing happens when I hit setup.
2. If I run the model and then hit setup again, the amount of sliver nitrate in the data box should be 0 - why isn't it?
3. Why isn't my silver nitrate slider working?
4. Why aren't the copper nitrate agents moving?
