Build an Commission Dashboard

We are going to use code from easy reports to build a commission web dashboard. Code will be provided. Requirements are as follows: - Keep the filters but what we want to do is to calculate commissions based on employee - we can get rid of a lot of the extras like the graphs most of the tables but what we want is to be able to show a commission based on a percentage for an employee - The user would select an orders date range, select an employee, and any other types of variables for the order, then they would select a commission percentage it would show the table of orders like it is now but at the bottom it would list the employee and the commission amount based on the percentage ML
