我有一份按年龄和性别划分的人口统计报告。当我遇到没有女性员工的部门时，我的一个字段返回#Error。我已经尝试了我能想到的一切来避免这种情况，但还没有找到解决方案。

伪逻辑是，如果女性员工的数量 = 0，则返回“N/A”，否则给我该部门女性员工的平均年龄。我也尝试过返回零或空格。当计数为零时，所有努力都会返回#Error。

我最近的尝试如下：

=iif(sum(iif(Fields!CustGender.Value = "F",1D,0D),"ReportDataset") = 0D,"N/A",Int(Avg(IIF(Fields!CustGender.Value = "F", CDec(Fields!Age.Value),Nothing),"ReportDataset")))

=iif(sum(iif(Fields!CustGender.Value = "F",1,0),"ReportDataset") = 0,"N/A",Int(Avg(IIF(Fields!CustGender.Value = "F", CDec(Fields!Age.Value),Nothing),"ReportDataset")))

=iif(sum(iif(Fields!CustGender.Value = "F",1D,0D),"ReportDataset") = 0D," ",Int(Avg(IIF(Fields!CustGender.Value = "F", CDec(Fields!Age.Value),Nothing),"ReportDataset")))

=iif(sum(iif(Fields!CustGender.Value = "F",1,0),"ReportDataset") = 0," ",Int(Avg(IIF(Fields!CustGender.Value = "F", CDec(Fields!Age.Value),Nothing),"ReportDataset")))

新的消息：

将“Nothing”更改为 0D，错误消失，但计算不正确，因为我在我的 Avg 计算中添加了一堆零值，因此 37 岁的平均年龄变为 10 或类似的东西。

=iif(sum(iif(Fields!CustGender.Value = "F",1D,0D),"ReportDataset") = 0D,"N/A",Int(Avg(IIF(Fields!CustGender.Value = "F", CDec(Fields!Age.Value),Nothing),"ReportDataset")))  -- Fails

=iif(sum(iif(Fields!CustGender.Value = "F",1D,0D),"ReportDataset") = 0D,"N/A",Int(Avg(IIF(Fields!CustGender.Value = "F", CDec(Fields!Age.Value),0D),"ReportDataset")))  -- Works

伊恩的数据：

这是部门 05 of 26。第五个字段是性别，最后一个字段是我想要平均的年龄。

解决了！！

在询问“这是一位女性”时，我无法将零值作为“错误”评估的返回值，因为随后我的样本量随着十几名男性员工的增加而增加，然后 Avg 函数被抛弃了，因为我有所有这些年龄为 0 岁的男性。因此，我的女员工显示为 8 岁、11 岁、14 岁。关键是在我的 iif 的“真实”部分中，我正在转换为 Int，这意味着传回“Nothing”是一种无效的做法。通过删除我的 Int，我可以将“Nothing”放回原处，从而避免臃肿的样本量，并从 Avg 返回一个有效值。 

=iif(sum(iif(Fields!CustGender.Value = "F",1D,0D),"ReportDataset") = 0D,"N/A",Avg(IIF(Fields!CustGender.Value = "F", CDec(Fields!Age.Value),Nothing),"ReportDataset"))
