Hello! I am trying to view the results of a bunch of processes I put in, mostly natural gas and some diesel/oil power plants, but I am getting this error and I do not know what it is referring to. If I click on OK, the screen moves to the Secondary Fuels branch.

I added multiple processes for the same technology (natural gas) because my data is given for individual power plants and not for the technology as a whole.

I completed the LEAP training exercise (2015) exercise 1 without any issue. The only difference in model set-up I notice (apart from the power plants) is that the dispatch rule is set to PercentShare. I have entered TimeSlice data and Peak Load Curve data also.

For reference, I have included another screenshot of the tree.

Also, I am a beginner; sorry if the query is lame!
