Not able to create a report for specific requirement

Content

Hi All,

I have a requirement, I have created a​ dff that is "Is this eligible for reimbursement?" on course page and in this dff there are 2 values one is No and another one is Yes, when I am selecting Yes then it will show category type dff with category A, category B and category.

And some of the course are reimbursement course and also in that course I have put some minimum and maximum price.

Now my requirement is that, I want to run a report, in the report I want to see how many learners has taken reimbursement course with which category and what is the minimum and maximum price for that course.
