I am looking to create a spreadsheet that my staff fill out, it then gives me a master sheet with all the data, then I import dynamically to my financial spreadsheet telling me the average cost of my client over the last 30 days.
I am looking to create an AVERAGE
formula of the last 30 days when Date = Today (Monday) (I want the weekday Monday as that's when staff hand in invoices)
Hope this makes sense, it's really tough!
Here's a video of me explaining my desired outcome

I've followed several guides & can't figure it out.
=ArrayFormula(iferror(query(average(if(today() - weekday(today(),3)-30)))))
I expected $90 average and I just get blank

您可以使用以下公式:
= AVERAGE(VLOOKUP(TODAY()-WEEKDAY(TODAY(),2)+ 1,A:H,2,FALSE),VLOOKUP(TODAY()-WEEKDAY(TODAY(),2)-6,A :H,2,FALSE),VLOOKUP(TODAY()-WEEKDAY(TODAY(),2)-13,A:H,2,FALSE),VLOOKUP(TODAY()-WEEKDAY(TODAY(),2)-20 ,A:H,2,FALSE))
要将其细分为各个组成部分,请从VLOOKUP结果中获取平均值:
VLOOKUP(TODAY()-WEEKDAY(TODAY(),2)+ 1,A:H,2,FALSE)
VLOOKUP正在查找当前日期的最后一个星期一:
TODAY()-WEEKDAY(TODAY(),2)+1
然后
TODAY()-WEEKDAY(TODAY(),2)-6
以此类推...
在工作表上使用时,您必须指定要在查询中参考的列,对于列B(brand1)使用: A:H,2,FALSE ),对于 colunm C(品牌2),请使用: A:H,3,FALSE),对于 colunm d(品牌3)使用: A:H,4,FALSE)等等...
