Hi Charlie,

I am working on modelling the energy trading in a multi-region area. After setting the variable on "Has Regional Imports" and "Regional Import Fraction" tabs, However, I cannot run the simulation.

The error message says: Invalid branch name: "Imports from ". Name "Imports from " contains reserved variable name "Imports".

I think the error was pointing at the tree branch that was automatically showed up after I put "Yes" on "Has Regional Imports" variable. Please see attached the error message and the tree branch.

Could you please tell me how to proceed with this? Thank you in advance.

Thank you Charlie.

Actually, I have another thing (not sure if it is also a bug or not).

The "Regional Import Fraction" tab is only showing up if I put "yes" on "Has regional imports" tab in "Current Accounts". It is not showing if I am working on any other scenarios.

Is it possible to change it? The purpose is so that we can work on some scenarios that is without energy trading among regions and other scenarios with energy trading.
