【问题描述】：
以下代码不起作用。我的 VLOOKUP 函数出现 2042 错误，但是无论我做什么都无法解决。我一直在使用 if ISERROR ，但它仍然无法正确捕获它，从而损害了我的整个宏。如果我运行本地窗口，您可以看到要搜索的值存储在数组“arr”中，如果在“目标”范围内未找到，则即使后续条目也返回 2042。
Sub test()
ThisWorkbook.Activate
Worksheets.add
Worksheets("Test4").Range("A1:T110").copy Destination:=ActiveSheet.Range("A1")
With ActiveSheet
Dim Search_Array As Variant
Search_Array = Range("C2", Range("C1").End(xlDown)) 'use this array to loop through the value to search for
Dim Target_MatchValue As Integer
Dim Target_Range As Range
Dim arr As Variant
Dim counter As Integer
Dim n As Integer
counter = 0
n = 0
Target_MatchValue = 0
For counter = LBound(Search_Array) To UBound(Search_Array)
Target_MatchValue = 0
Target_MatchValue = Application.Match(Search_Array(counter, 1), .Range("H2:H200"), 0) - 1
Set Target_Range = .Range(.Cells(2 + n, 8), .Cells(1000, 9))
arr = Application.VLookup(Search_Array(counter, 1), Target_Range, 2, False)
If IsError(arr) Then
.Range(Cells(1 + counter, 6), Cells(1 + counter, 6)).value = "N/A"
Else
.Range(Cells(1 + counter, 6), Cells(1 + counter, 6)).value = arr 'Return the value of the array in this cell
End If
Target_Range.Select
If Target_MatchValue = 0 Then
n = n + 1
ElseIf Target_MatchValue > 0 Then
n = n + Target_MatchValue
End If
Next counter

Set Target_Range = .Range(Cells(2 + n, 4), Cells(1000, 5)) 'this is supposed to work as a shifting range allowing to match entries without making repetitions. I used the MATCH function in order to set the start of the range. i.e. if there is a match in the target table the range will shift from the location of the match downwards. If the match is at on the same level then it does not shift the range in order to match the same-level entry afterwards it is supposed to shift by one unit in order to prevent repetitions.
