如何将工作簿设置为 fpath 和 listboxvalue

How do I set workbook as fpath & listboxvalue

Encounter Runtime Error 424, Object Required

下面的代码

 Public fpath as string, fwbk As Workbook


 Private Sub BtnCloseWoSaving_Click()
 'Error on code below
 Set fwbk = fpath & Me.ListBoxWbk.Value 
 End Sub

我正在使用用户表单打开文件、关闭和自动化数据。 停留在将打开的文件设置为工作簿的这个阶段。

提前感谢您的帮助(:

Public fpath as string, fwbk As Workbook


 Private Sub BtnCloseWoSaving_Click()
 'Error on code below
 Set fwbk = workbooks.open(fpath & Me.ListBoxWbk.Value )
  '    ...
 End Sub
