表达式中错位的括号

Question

再有一双眼睛来看这个就好了。我越弄乱它，就会收到两条错误消息之一。它要么需要另一个括号，要么不正确使用 True/False。我只是看着它有点沮丧。任何帮助将非常感激。这是漫长的一天。

=IIF((Sum(Fields!January.Value, "CDataSet")- Code.DivideBy(Fields!M191.Value, Sum(Fields!Totals.Value, "DataSet2")) < 0 
and (Sum(Fields!January.Value, "CDataSet")- Code.DivideBy(Fields!M191.Value, Sum(Fields!Totals.Value, "DataSet2")))> Sum(Fields!Variance.Value, "CDataSet")),"Red",
IIF((Sum(Fields!January.Value,"CDataSet")- Code.DivideBy(Fields!M191.Value, Sum(Fields!Totals.Value, "DataSet2"))) > 0 
and (Sum(Fields!January.Value, "CDataSet")- Code.DivideBy(Fields!M191.Value, Sum(Fields!Totals.Value, "DataSet2"))) > Sum(Fields!Variance.Value, "CDataSet")), "LimeGreen","Transparent")

Answer 1

当我将代码缩进到括号级别时，我得到：

=IIF(
  (
    Sum(Fields!January.Value, "CDataSet") - Code.DivideBy(
      Fields!M191.Value, Sum(Fields!Totals.Value, "DataSet2")
    ) < 0 
    and (
      Sum(Fields!January.Value, "CDataSet") - Code.DivideBy(
        Fields!M191.Value, Sum(Fields!Totals.Value, "DataSet2")
      )
    ) > Sum(Fields!ThresholdAging.Value, "CDataSet")
  ),
  "Red",
  IIF(
    (
      Sum(Fields!January.Value,"CDataSet") - Code.DivideBy(
        Fields!M191.Value, Sum(Fields!Totals.Value, "DataSet2")
      )
    ) > 0 
    and (
      Sum(Fields!January.Value, "CDataSet") - Code.DivideBy(
        Fields!M191.Value, Sum(Fields!Totals.Value, "DataSet2")
      )
    ) > Sum(Fields!ThresholdAging.Value, "CDataSet")
  ),
  "LimeGreen",
  "Transparent"
)

结论：内层IIF只有一个参数，外层IIF有五个。我认为您的意思是将最后两个字符串放在内部 IIF 中：

      ...
    ) > Sum(Fields!ThresholdAging.Value, "CDataSet"),
    "LimeGreen",
    "Transparent"
  )
)
