错误：BC30201 IN ssrs

Question

我正在

  

文本运行的值表达式   ＆＃39; PAYEE_NAME.Paragraphs [0] .Textruns [0]＆＃39;包含错误BC30201＆＃34;为：

=iif(isnothing(First(Fields!PAYEE_NAME.Value, "AddressDetails")),"",(First(Fields!PAYEE_NAME.Value, "AddressDetails")+vbcrlf))+
iif(isnothing(First(Fields!ADDRESSLINE1.Value, "AddressDetails")),"",(First(Fields!ADDRESSLINE1.Value, "AddressDetails")))

但不是为了：

=replace(iif(isnothing(First(Fields!PAYEE_NAME.Value, "AddressDetails")),"",(First(Fields!PAYEE_NAME.Value, "AddressDetails")+vbcrlf))+
iif(isnothing(First(Fields!ADDRESSLINE1.Value, "AddressDetails")),"",(First(Fields!ADDRESSLINE1.Value, "AddressDetails")))
," ","")

为什么呢？我该如何解决这个问题？第二个表达式删除了单词之间的空格，我不需要这样做。我想要它，如果有收款人的收款人姓名然后显示它，如果没有去第二行并做同样的事。
