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!	W	X	Y	Z	Quantity 4	Item 4	Quantity 5	Item 5
100	BDM-250	50	AC Intercon Cable	50	End Cap
130	AXN6P610T250BW	130	AXN-P6T270BB
36	AXN6P610T250BW	36	BDM-250	1	BDG-256	3	AC Intercon Cable	3	End Cap
50	TS-S420	3	AC Intercon Cable	600	MR-SW-HP-35S
50	AXN6P610T250SW	3	End Cap	600	BDM-250	3	AC Intercon Cable
24	BDM-250	3	AXN6P610T250BW	22	BDG-256	3	End 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!
