SSRS中的VB表達式導致錯誤

Question

我正在為SSRS更改背景單元格顏色的表達式。 我在第二個IIF語句中不斷收到錯誤，我不知道為什么，也許有人可以發現我犯的錯誤？

這是我最初表達的意思。

=IIF((Fields!DriveLetter.Value = "F:" OR Fields!DriveLetter.Value = "T:") AND (Fields!FileType.Value = "MDF" OR Fields!FileType.Value = "NDF"), "Lime",
IIF((Fields!DriveLetter.Value = "G:" OR Fields!DriveLetter.Value = "U:") AND (Fields!FileType.Value = "LDF"), "Lime", "Tomato") )

我又添加了一個IIF語句，並添加了邏輯，這導致了錯誤。 我一直在玩它，但是找不到錯誤。

=IIF((Fields!DriveLetter.Value = "F:" OR Fields!DriveLetter.Value = "T:") AND (Fields!FileType.Value = "MDF" OR Fields!FileType.Value = "NDF"), "Green",
 IIF(Fields!DriveLetter.Value = "G:" OR Fields!DriveLetter.Value = "U:") AND (Fields!FileType.Value = "LDF"), "Green",
 IIF(Fields!DriveLetter.Value = "C:") AND (Fields!Database_Name.Value = "master" OR Fields!Database_Name.Value = "model" OR Fields!Database_Name.Value = "msdb" 
                                                                                 OR Fields!Database_Name.Value = "tempdb"), "Lime", "Red" ) 

謝謝。

掛鈎設置不正確：

IIF(((Fields!DriveLetter.Value = "F:" OR Fields!DriveLetter.Value = "T:") AND
(Fields!FileType.Value = "MDF" OR Fields!FileType.Value = "NDF")), "Green", 
IIF(((Fields!DriveLetter.Value = "G:" OR Fields!DriveLetter.Value = "U:") AND 
(Fields!FileType.Value = "LDF")), "Green", IIF(((Fields!DriveLetter.Value = "C:") AND 
(Fields!Database_Name.Value = "master" OR Fields!Database_Name.Value = "model" OR 
Fields!Database_Name.Value = "msdb" OR Fields!Database_Name.Value = "tempdb")), "Lime", 
"Red" )))
