Microsoft Excel -vba 错误

Question

有人能告诉我为什么函数显示类型不匹配吗If Not j Is Nothing Then

我正在尝试制作一个宏来在一张工作表（此处称为报告表）中搜索变量列表（该变量旁边的单元格具有特定值），另一张工作表具有这些变量及其新值，并将它们复制到报告表以进行比较。

如果我声明j为，range那么我将无法搜索，因为我必须删除.select并添加设置j到下面的行

j = Range("h1:q3000").find(What:=variablename).Select

Option Explicit

Sub search_and_find()

Dim datasheet As Worksheet
Dim reportsheet As Worksheet
Dim variablename As String
Dim finalrow As Integer
Dim i As Integer
Dim j As String
Dim k As Integer
Dim finalrsheet As Integer

Set datasheet = Sheet1
Set reportsheet = Sheet2

reportsheet.Select
Range("a1").Select
With ActiveSheet
finalrsheet = .Cells(.Rows.Count, "A").End(xlUp).Row
End With
 For i = 2 To finalrsheet
    Cells(i, 1).Select
    Selection.Copy
    Sheet3.Activate
    Range("a1").PasteSpecial
    variablename = Range("a1")
    datasheet.Activate
    j = Range("h1:q3000").find(What:=variablename).Select
        If Not j Is Nothing Then
        Selection.Offset(0, 5).Copy
        reportsheet.Activate
        Cells(i, 4).PasteSpecial
        Else
        reportsheet.Activate
        Cells(i, 5).Value = "Need to find Manually"
        End If
 Next i
    reportsheet.Activate
    For k = 2 To finalrsheet
        If Cells(k, 5).Value = "Need to find Manually" Then
        Cells(k, 5).Value = "Need to find Manually"
        ElseIf Cells(k, 2).Value = Cells(k, 4).Value Then
        Cells(k, 5).Value = "No change"
        Else
        Cells(k, 5).Value = "Changed"
        End If
    Next k
End Sub
