How do I add columns based off a parameter in ssrs report

Question

I am creating a report on Visual Studio and I need to sum the columns based on the year. My data has number of packages for the year 2019 and 2020. I want a grand total for 2019 and for 2020 as the last column on my report. I try to sum it up , and it sums up 2019 and 2020 for my parameter and gives me that total. Any help here will be appreciated
