问题

运行Excel宏时反复触发Run-time error '5': Invalid procedure or call argument错误，宏和对应文件自上次使用后未做任何修改，但更换了新笔记本。不确定是Excel权限问题还是宏本身故障，报错指向代码中的这一行：

ProductName = Left(ProductHolder, InStr(ProductHolder, "Strategy") - 2)

完整宏代码片段如下：

Sub SS_Cleanup()
    ActiveWorkbook.RefreshAll
        Sheets("report").Select
    Columns("H:H").Select
    Range("H:H").Activate
    Selection.Replace What:="Global Equity, benchmarked to the MSCI ACWI", _
        Replacement:="", LookAt:=xlPart, SearchOrder:=xlByRows, MatchCase:= _
        False, SearchFormat:=False, ReplaceFormat:=False
    Selection.Replace What:="ESG High Conviction, benchmarked to the MSCI ACWI", _
        Replacement:="", LookAt:=xlPart, SearchOrder:=xlByRows, MatchCase:= _
        False, SearchFormat:=False, ReplaceFormat:=False
    Selection.Replace What:="International Conviction, benchmarked to the MSCI ACWI", _
        Replacement:="", LookAt:=xlPart, SearchOrder:=xlByRows, MatchCase:= _
        False, SearchFormat:=False, ReplaceFormat:=False
    Selection.Replace What:= _
        "No Animal Testing (Medical/Pharma Allowed) Strategy benchmarked to the S", _
        Replacement:= _
        "No Animal Testing (Medical/Pharma Allowed) Strategy benchmarked to the S&P 1500" _
        , LookAt:=xlPart, SearchOrder:=xlByRows, MatchCase:=False, SearchFormat _
        :=False, ReplaceFormat:=False
    Selection.Replace What:= _
        "Gifting", _
        Replacement:= _
        "Not Applicable" _
        , LookAt:=xlPart, SearchOrder:=xlByRows, MatchCase:=False, SearchFormat _
        :=False, ReplaceFormat:=False
        
    Dim i, n As Integer
    Dim ProductHolder, Product As String
    Dim ProductName As String
            

            i = 2
           

    Do While Workbooks("SS Data Converter.xlsm").Worksheets("report").Cells(i, 1) <> ""
            

            'enters the product in last column
            ProductHolder = ""
            Product = ""
            ProductName = ""
            

            ProductHolder = Workbooks("SS Data Converter.xlsm").Worksheets("report").Cells(i, 8)
            If ProductHolder <> "" And ProductHolder <> "Not Applicable" And ProductHolder <> "Jointly Managed" Then
                Product = Right(ProductHolder, Len(ProductHolder) - InStr(ProductHolder, "S&") + 1)
                ProductName = Left(ProductHolder, InStr(ProductHolder, "Strategy") - 2)
            End If
            Select Case Product
            Case "S&P 1500"

错误根本原因分析

Left函数参数无效：报错核心是InStr(ProductHolder, "Strategy")返回了0（即当前ProductHolder字符串中找不到"Strategy"），计算0-2=-2后，Left函数的第二个参数不能为负数，直接触发参数无效错误。
代码健壮性缺失：原代码未对InStr的返回值做有效性判断，之前能正常运行是因为所有符合条件的ProductHolder都包含"Strategy"字符串，换笔记本后可能数据出现了新内容（或因Excel区域/语言设置导致字符串匹配异常），触发了代码漏洞。
权限问题可排除：权限类错误通常表现为文件无法访问、宏被禁用等，不会触发参数无效的运行时错误，因此可以排除权限因素。

修复方案

增加有效性判断：在调用Left函数前先检查InStr的返回值，避免负数参数：

If ProductHolder <> "" And ProductHolder <> "Not Applicable" And ProductHolder <> "Jointly Managed" Then
    Product = Right(ProductHolder, Len(ProductHolder) - InStr(ProductHolder, "S&") + 1)
    Dim strategyPos As Integer
    strategyPos = InStr(ProductHolder, "Strategy")
    If strategyPos > 0 Then
        ProductName = Left(ProductHolder, strategyPos - 2)
    Else
        ' 根据需求处理无"Strategy"的情况，比如赋值为空或原字符串
        ProductName = ""
    End If
End If

检查数据一致性：确认H列中符合条件的单元格是否全部包含"Strategy"，若有新的内容格式，需同步更新宏中的字符串匹配逻辑。
优化代码冗余：避免重复调用InStr，提升代码运行效率（如上述代码中用变量存储strategyPos）。
