如果列x包含字符串，则将值乘以-1

Question

Basically what i want to do is to express my excel column sum in -ve if the value in Action is Sell . If its Buy then don't do anything. Currently, I am doing sum like =B2+C2 but it will always be in +ve no matter if it is representing a purchase or sell order.

Here is some sample data

Notice how Net column shows +ve value even though one value is Sell and the other one is Buy . I want Sell to be displayed as +ve value and Sell to be shown as -ve value.

Answer 1

我能够使用=IF(B2="Buy", G2+F2, -1*(G2+F2))解决我的问题。
