Monte Carlo simualtion yielding 0 results

Question

Hello, I'm trying to run Monte Carlo simulations and keep getting 0 results. I've tried different uncertainty distributions and different LCIA methods. I've run it for a different project before and the results all made sense so it just seems to be for the product systems for this project. Does anyone know what I'm doing wrong? Thanks

see other posts here - the database / processes you use and especially the exchanges (inputs and outputs of processes) need to have uncertainty information, in the system you calculate, at least some of them, otherwise you always get the same result in the simulation.
