Aggregate multiple rows of data to one if conditions are met

Hi xladept, the code you posted for me works great and I am using it daily... I love it so much, now I am trying to implement it on another sheet, with different row/column set up. I tried to make changes but since I am not familiar with scripting dictionaries wasn't able to get it running.

On the sheet attached, I am trying to aggregate the data based on if column A, C, F, H are the same, and while aggregating SUM column G, and find weighted average in column I, essentially exactly how the other code worked just changing up a find columns and where the data starts...

Praying you can help me this last time on this
