Excel VBA-运行时错误'9'，下标超出范围

我真的很感谢我能为此提供的任何帮助。

我正在尝试遍历一列以查找重复的名称，然后从同一行中获取该名称和其他一些数据，并将它们放入要使用其他功能的2D数组中，但是它不起作用。

我真的需要您的帮助，弄清楚为什么我不保存数据就无法重新数组化。

Dim oRange As Range, aCell As Range, bCell As Range
Dim ws As Worksheet
Dim SearchString As String, FoundAt As String
Dim tArray() As Variant
Dim iR As Long
Dim LastRow As Long
Dim LastCol As Long

'name of the worksheet
Set ws = Worksheets("VML Daily")

'column 6 has a huge list of names
Set oRange = ws.Columns(6)

'the keyword (there are 7 'ABC Company 1' in the column above)
SearchString = "ABC Company 1"

'Find keyword in column
Set aCell = oRange.Find(What:=SearchString, LookIn:=xlValues, _
            LookAt:=xlWhole, SearchOrder:=xlByRows, SearchDirection:=xlNext, _
            MatchCase:=False, SearchFormat:=False)

'find last row and column number
LastRow = Range("A1").End(xlDown).Row

'redimensioning based on maximum rows
ReDim Preserve tArray(1 To LastRow, 1 To 3) As Variant

'if search finds something
If Not aCell Is Nothing Then
    Set bCell = aCell
    FoundAt = aCell.Address
    iR = 1

    tArray(1, 1) = aCell
    tArray(1, 2) = aCell.Offset(0, 33)
    tArray(1, 3) = aCell.Offset(0, 38)

    'continue finding stuff until end
    Do
        Set aCell = oRange.FindNext(After:=aCell)

        If Not aCell Is Nothing Then
            If aCell.Address = bCell.Address Then Exit Do
            FoundAt = FoundAt & ", " & aCell.Address
            tArray(iR, 1) = aCell
            tArray(iR, 2) = aCell.Offset(0, 33)
            tArray(iR, 3) = aCell.Offset(0, 38)
            iR = iR + 1
        Else
            Exit Do
        End If
    Loop

    'redim'ing the array to the amount of hits I found above and preserve the data
    'Here's where it error's out as "Subscript out of range"
    ReDim Preserve tArray(1 To iR, 1 To 3) As Variant
Else
    MsgBox SearchString & " not Found"
    Exit Sub
End If
