運行VBA代碼並得到運行時錯誤'91'

Question

當我運行下面的代碼時，出現運行時錯誤'91'：對象變量或塊變量未設置。它突出顯示了在set rng函數中的編號下面的編碼，任何人都知道我需要對代碼執行什麼操作才能使其不出錯？

Answer 1

您應該測試您嘗試使用找到的範圍的屬性之前搜索值居然發現：

Set rng = wsDataAll.Cells.Find(ListBox2.List(index), LookAt:=xlWhole) 
If not rng Is Nothing then 
    Set rng = Range(rng.Offset(0, 14), rng.Offset(0, 14).End(xlDown)) 
Else 
    Msgbox ListBox2.List(index) & " not found" 
    Exit Sub 
End If 

例如。
