Sumifs

Hey,

I want sum the values in column C (R1) with next conditions:
1 - i canīt change the order of any variable,
2 - i have sum the values of column C (R1) following the conditions in column B (E2),
3 - and last condition, i only want sum last four values in column C (R1), for each variable of column B (E2) (for example: If i have the formula in cell D69 the output should be 2, if i have the formula in cell D70 the output should be 2, if i have the formula in cell D71 the output should be 2, and if i have the formula in cell D72 the output should be 0).
What i want is: in d2 a formula with this conditions, in d3 a formula with this conditions, in d4 a formula with this conditions, and so on. The reason to this form is automate the formula to calculate last 4 values of each variable in cell B2, B3, B4....
Itīs possible?
How can i do this?
