Sum a range of cells

Hello folks

I'm sure this is very easy but I am struggling with it because of multiple rows...

Column B has a list of names (e.g. B8:B12 = Alpha, B13:B17 = Beta etc)
Row 10 has years (e.g. D10:F11 = 2021, G11:M11 = 2022, etc)
Below each year and to the right of each name are values

I'm trying to write a formula to calculate the total value for each name for each year

2021 2022 2023
Alpha $?
Beta $?

Kindly help me if possible. Or let me know if this is unclear and I will try to explain better.
