I have done all exercises of LEAP but in exercise 4 which is cost benefit analysis the results didn't come for fuel production.

I have tick all the costs in legend but it only shows values of Capital cost,fixed O and M and Variable O and M.

Kindly help me for this.

Thanks.

Be sure that you've selected a part of the tree than includes all types of costs below it. Since fuel production or import costs enter the model through the Resources branches, you would need to select to top-most branch of the tree to view all costs.

If this does't solve you problem, please include a careful description and screenshot of how you've set up your chart.
