如何根据Excel中的多个If计算总和？

背景是，我正在制作预算电子表格。 我在不同的日子有不同的账单。 （即周一到期的账单和10日到期的账单）

我想要一个函数，将在D列中放入适当数量的资金，并在E列中说明资金进/出的原因。

目前我有两个不同的公式（可能是错误的）。

E列的公式：（已经在文档中，似乎工作正常，除了我不能添加额外的文本到单元格）

=IF(DAY(C36)=7," Amy Pay","")&IF(DAY(C36)=22," Amy Pay","")&IF(DAY(C36)=8," Family Bills","")&IF(DAY(C36)=6," Dollar Shave Club","")&IF(DAY(C36)=2," Amy Cap One VISA","")&IF(DAY(C36)=3," Chase VISA","")&IF(DAY(C36)=8," Being Smart","")&IF(DAY(C36)=17," Gym","")&IF(DAY(C36)=11," Netflix","")&IF(DAY(C36)=19," Cap One MC","")&IF(DAY(C36)=29," CenturyLink","")&IF(DAY(C36)=6," Haley Cap One Visa","")&IF(DAY(C36)=10," SRP","")&IF(DAY(C36)=23, "Car Payment","")&IF(DAY(C36)=30, "Rent","")&IF((B36)="Mon"," Monday","")&IF((B36)="Fri"," Friday","")&IF((B36)="Fri"," Haley Pay","") 

D列的公式：（不在列中，因为它不工作，我想要的）

 =IF(DAY(B40)=7,"1474.22","")&IF(DAY(B40)=22,"1474.22","")&IF(DAY(B40)=8,"-100","")&IF(DAY(B40)=6,"-9","")&IF(DAY(B40)=2,"-100","")&IF(DAY(B40)=3,"-100","")&IF(DAY(B40)=8,"-400","")&IF(DAY(B40)=17,"-20.05","")&IF(DAY(B40)=11,"-8.63","")&IF(DAY(B40)=19,"-450","")&IF(DAY(B40)=29,"-50","")&IF(DAY(B40)=6,"-150","")&IF(DAY(B40)=10,"-200","")&IF(DAY(B40)=23,"-325","")&IF(DAY(B40)=30,"-500","")&IF((A40)="Mon","-125","")&IF((A40)="Fri","-325","")&IF((A40)="Fri","400","")

问题是在列D中，而不是提供数字的总和，它列出列中的数字。

我有一个build议添加= SUM（在IF前面的函数，但是当我这样做的时候，#VALUE！就是这个字段的结果）使用这个公式:(查看图像通过改变附加文本到/ CVs0f1v）

 =SUM(IF(DAY(B40)=7,"1474.22","")&IF(DAY(B40)=22,"1474.22","")&IF(DAY(B40)=8,"-100","")&IF(DAY(B40)=6,"-9","")&IF(DAY(B40)=2,"-100","")&IF(DAY(B40)=3,"-100","")&IF(DAY(B40)=8,"-400","")&IF(DAY(B40)=17,"-20.05","")&IF(DAY(B40)=11,"-8.63","")&IF(DAY(B40)=19,"-450","")&IF(DAY(B40)=29,"-50","")&IF(DAY(B40)=6,"-150","")&IF(DAY(B40)=10,"-200","")&IF(DAY(B40)=23,"-325","")&IF(DAY(B40)=30,"-500","")&IF((A40)="Mon","-125","")&IF((A40)="Fri","-325","")&IF((A40)="Fri","400","")) 

关于如何让所有的东西填充和适当的总和的任何想法？

如果您从第一个工作公式中select所有选项并更改检索方法，您将拥有更多function的工作表，可以轻松地接受新的添加项目和计划修改。

1. 在右边的几个未使用的列中，在每个月的date和发生的操作。 我正在使用列Y和Z.你有两个事件发生在六号，所以我把它们放在一起。
2. 在其他一些未使用的列中使用星期几和相关的文本。 我已经使用V＆W列。星期天的默认值是1。
3. 在E36中使用这个公式，
   =TRIM(IFERROR(VLOOKUP(DAY(C36),$Y:$Z, 2, FALSE), "")&" "&IFERROR(VLOOKUP(WEEKDAY(C36),$V:$W, 2, FALSE), ""))
4. 根据需要填写。

如果您想要B列中的星期几，请使用=C36并使用ddd或dddd的自定义数字格式。

Answer 2

你连接看起来像数字的文本string。 你可能想要添加实际的数字：

 =SUM(IF(DAY(B40)=7,1474.22,0) + IF(DAY(B40)=22,0) + ... 

尽pipe每当我看到一个复杂的公式时，我会考虑寻找一个不同的解决scheme – Vlookup浮现在脑海。

另外，用VLOOKUP表，你会看到你有一些冲突 – 例如：你列出了相同的条件B40 = 8返回两个不同的值; 和A40 = Fri的条件相同，也返回两个不同的值。
