奇怪的#VALUE!错误

Strange #VALUE! error

请看一下这个错误:

这里有两个函数:

Public Function CompareExtra(r1 As Range, r2 As Range) As Long
   Dim r As Integer, v As Variant, v2 As Variant
   Dim rr1() As String
   Dim rr As Range
   rr1 = Split(r1, ",")
   For r = LBound(rr1) To UBound(rr1)
      v = --Trim(rr1(r))
      If v <> 0 And v <> "" Then
         For Each rr In r2
            v2 = rr.Value
            If v = v2 Then CompareExtra = CompareExtra + 1
         Next rr
      End If
   Next r
End Function


Function getLeast(rng As Range, leastXValues As Long, maxValue As Long, displacement As Long, Optional Sorted As Boolean = True) As String
  Dim d As Object, AL As Object
  Dim i As Long, j As Long
  Dim a As Variant

  Set d = CreateObject("Scripting.Dictionary")
  Set AL = CreateObject("System.Collections.ArrayList")
  a = rng.Value
  i = UBound(a, 1)
  j = UBound(a, 2)
  Do
    If a(i, j) <> 0 Then d(a(i, j)) = a(i, j)
    j = j - 1
    If j = 0 Then
      j = UBound(a, 2)
      i = i - 1
    End If
  Loop Until i = 0
  For i = 1 To maxValue
    d(i) = i
  Next i
  a = d.Items()
  For i = UBound(a) - displacement To UBound(a) - displacement - leastXValues + 1 Step -1
    AL.Add a(i)
  Next i
  If Sorted Then AL.Sort
  getLeast = Join(AL.ToArray, ", ")
End Function

我不明白为什么如果我从一个单独的单元格中获取 getLeast() 的结果 - 一切正常,但如果我将它直接添加到 CompareExtra(),它会抛出一个错误..

简单的解决方案是使用变体:

Public Function CompareExtra(r1 As Variant, r2 As Variant) As Long
Function getLeast(rng As Range, leastXValues As Long, maxValue As Long, displacement As Long, Optional Sorted As Boolean = True) As Variant
