如果其他单元格与特定值匹配，如何在公式中引用特定单元格

Question

Thanks so much for looking at my question. I am trying to create a formula that subtracts a specific value from another formula, However. that specific value may change.

Example:

A       B      C      D 

1       1      100    =(2000 - ( if A = 1, i want to subtract the C value where B =1))

1       2      250

1       3      310

1       4       .

2       1

2       2                =((2000 - ( if A = 2, i want to subtract the C value where B =1))

2       3

2       4 

3       1

3       2

3       3

3       4

(A,B,C,D are the columns)

Hopefully this makes sense. I am trying to subtract the C value that goes along with the B1 value for each different A.

I was thinking an index match of some sort but wasnt exactly sure how to do that when the A's change. Thanks so much in advance for help!

Answer 1

INDIRECT or INDEX functions can help you. See this answer .

Answer 2

Would something like a nested if function work for you here? For example:

=IF(A2=1,IF(B2=1,2000-C2,"Enter calculation if B2<>1"),"Enter calculation if A2"<>1)

If this works, then you can simply copy/paste the function down the rows in column D.
