    Hi From France ! This is the best explanation I've ever seen. You made me understand List.Accumulate... At least ! Thanks a lot🙏🙏🙏

    List.Accumulate is like the PQ problem child (along with Table.Buffer), but that was a darn good explanation.

      glorious! thank you! yes these are always a bit tricky to explain!

      What are you talking about?
      Not a problem child at all, just a very cool (fixed scope) iterator with a State variable.

    2:30 No, “current” (I just use “i”) is not the “current state of your variable”, it’s the loop variable that takes on every value in the list, provided in the first argument of List.Accumulate.

    I didn't see your column A (total) update when you added column F (Stock James). It should, right? Regardless, I really liked your explanation of List.Accumulate! It's a tough one to wrap your head around and this made it easy to understand. Thanks!

    I have a situation where I have a parent child relationship in a multiple rows. I need to do a market basket transform where I need to pivot the parent child into one row to see what combinations are selling . Any guidance how could I do that here

    Help!!! I keep getting "Expression.SyntaxError: Token ')' expected." every time I type in "= list.accumulate(Source,1, (state, current),=> state * current)". [obviously without qutation marks and source being the original query >> = {1,2,3,4,5}] I don't know about anyone else, but I count 2*open brackets and 2*closed brackets. What am I missing? (Excel 365). Oh btw, are the spaces in the syntax necessary?
