Hi sir , I hope you're doing well.

Regarding the cost-benefit analysis of Training Exercise #4, Sir, I have a problem from the past 4 days. I've watched training videos, but my results are still incorrect. Could you kindly advise me on how to get the correct results? This is screenshoot. Please advise me sir. I will thank to you.

It's maily caused by the wrong selection of the unit and scenario when you first do the exercise. I'd suggest to check the data unit, scenario selection, and settings. Hope this helps.

Best wishes,

Liya
