Hello I need to make a sumproduct with general conditions. 您好，我需要在一般条件下sumproduct 。 The correct values is shown in cell B6 , B7 and B8 正确的值显示在单元格B6 ， B7和B8

In cell B6 I have this formula =A1*A2+B1*B2+C1*C2 to understand what is the result that I expected. 在单元格B6我有这个公式=A1*A2+B1*B2+C1*C2以了解我期望的结果是什么。
In B7 is =D1*D2+E1*E2 and so on... 在B7是=D1*D2+E1*E2 ，依此类推...

I've tried with this formula =SUMPRODUCT(A3:G3=A6,A1:G1,A2:G2) in cell B6 but the result is 0. 我尝试在单元格B6使用此公式=SUMPRODUCT(A3:G3=A6,A1:G1,A2:G2) ，但结果为0。

2 个解决方案

Use =SUMPRODUCT(1*(A3:G3=A6),A1:G1,A2:G2) in cell B6 . 在单元格B6使用=SUMPRODUCT(1*(A3:G3=A6),A1:G1,A2:G2)

Better still use =SUMPRODUCT(1*(A$3:G$3=A6),A$1:G$1,A$2:G$2) 最好还是使用=SUMPRODUCT(1*(A$3:G$3=A6),A$1:G$1,A$2:G$2)

and you will be able to copy the formula from B6 to B7:B8 and it will behave as you want. 然后您就可以将公式从B6复制到B7:B8 ，它将按您的意愿运行。

From this page , I learned that "--" can transform True and False values into 1's and 0's. 通过此页面，我了解到“-”可以将True和False值转换为1和0。

That's probably why you are getting 0, the formula you use adds boolean values to numerical values. 这可能就是为什么您得到0，所使用的公式将布尔值添加到数值中的原因。

So the formula you are looking for in cell B6 is =SUMPRODUCT(--(A3:G3=A6),A1:G1,A2:G2) . 因此，您在单元格B6中寻找的公式是=SUMPRODUCT(--(A3:G3=A6),A1:G1,A2:G2) 。

Tested on Excel 2010, it worked. 在Excel 2010上进行了测试，它可以正常工作。
