Hi, I have an INVENTORY sheet that has different invoice details by row with 'number sold' and 'item' in consequetive  columns, starting with Col U Ex:

U#VALUE!WXYZQuantity 4Item 4Quantity 5Item 5
100BDM-25050AC Intercon Cable50End Cap
36AXN6P610T250BW36BDM-2501BDG-2563AC Intercon Cable3End Cap
50TS-S4203AC Intercon Cable600MR-SW-HP-35S
50AXN6P610T250SW3End Cap600BDM-2503AC Intercon Cable
24BDM-2503AXN6P610T250BW22BDG-2563End Cap

I want to filter each unique item with the SUM of the sales across all rows. Although there may be a more elegant way to do this for col U-EF, I can only think of filtering per column. like this:
In V1, in order to calculate the total sales for each  unique item, I am using:

=ArrayFormula(QUERY(IF({1,0},IFERROR(REGEXEXTRACT(V2:V,"^([a-zA-Z]+)")),Inventory!B2:B),"select Col12, sum(Col1) where Col2 != '' group by Col2 label sum(Col1) ''",0))

but it is not working. If anyone can help me, I would be most grateful.

Here is a link to the sheet.
and it is the Expense tab
Thanks in advance for any advise!
