Question

目前有以下代码：

    Sub StartReport()
**Dim Month As String**
 Dim Data_sht As Worksheet
 Dim Pivot_sht As Worksheet
 Dim StartPoint As Range
 Dim DataRange As Range
 Dim PivotName As String
 Dim NewRange As String

 ' Set variables equal to data sheet and pivot sheet
 **Set Month = "B2"**

 Set Data_sht = ThisWorkbook.Worksheets.**Month**

 Set Pivot_sht = ThisWorkbook.Worksheets("Controller Report")

 'Enter in Pivot table name
 PivotName = "PivotTable1"

 'Dynamically retrieve range address of data
 Set StartPoint = Data_sht.Range("A1")
 Set DataRange = Data_sht.Range(StartPoint, StartPoint.SpecialCells(xlLastCell))
 NewRange = Data_sht.Name & "!" & _
 DataRange.Address(ReferenceStyle:=x1R1C1)

 'make sure every column in data set has a heading and is not blank (error prevention)
 If WorksheetFunction.CountBlank(DataRange.Rows(1)) > 0 Then
 MsgBox "One of your data columsn has a blank heading." & vbNewLine _
 & "please fix and re-run!.", vbCritical, "Column heading Missing!"
 Exit Sub
 End If

 'Change pivot table data source range address

 Pivot_sht.PivotTables(PivotName).ChangePivotCache _
    ThisWorkbook.PivotCaches.Create( _
    SourceType:=xlDatabase, _
    SourceData:=NewRange)

'Ensure pivot table is refreashed
Pivot_sht.PivotTables("PivotTable1").RefreshTable

'Complete Message
MsgBox PivotName & " 's data source range has been successfully updated!"

End Sub

加粗的部分（在它们之前和之后有**）是我遇到困难的地方。我希望从我创建的下拉菜单中选取数据，该菜单上有所有选项卡的名称。下拉位于单元格＆＃34; B2＆＃34;在第一个选项卡上。从此下拉列表中选择月份时，我希望选择具有相同名称的数据表作为数据透视表的数据源。请帮忙
