Summing all previous numbers with criteria

[des378]

Hi again,​

Looking to sum all previous numbers based on criteria. Need output to be a horizontal spilled range.. Example below. I have a formula but it uses the "OFFSET" function and I need to do this without volatile functions in Excel. Thanks in advance!

Ex
2024-11-18 2024-05-12 2024-10-09 2024-11-18 2024-10-09
50 100 30 75 90

Output all summed previous numbers as a horizontal spilled range that are equal to 2024-11-18
Output:
2024-11-18 2024-05-12 2024-10-09 2024-11-18 2024-10-09
50 n/a n/a 125 n/a

If it could also display n/a or 0 as a value that would be great (e.g changeable between both).
