Hello,
In this project, I have a schedule source in the "Arrivals" process flow, and I created ten process flow variables (Pic1) and connected them with the dashboard's model input so I could change the rate of arrivals for the tokens from there (Pic2), and it worked. However, every time I reopen the model, these exceptions appear (Pic3), and I start assigning the process flow variables again in the schedule source (Pic4).
Pic1
Pic2
Pic3
Pic4
How can I stop this from happening again?
