Excel VBA-無法找到導致“運行時錯誤91”的錯誤

Question

我有以下代碼，這導致

運行時錯誤91-未設置對象變量

我已將每個工作簿，工作表和變量調暗，但不能消除錯誤。

    Dim r As Long, c As Long
    Dim snowq As Workbook, CAQual As Workbook, qsum As Worksheet, CAqsum As Worksheet
    For r = 2 To 8
        For c = 2 To 4
            combinedReports.Worksheets("combinedQualities").Cells(r, c).Value = _
                snowq.Worksheets("qsum").Cells(r, c).Value + CAQual.Worksheets("CAqsum").Cells(r, c).Value
        Next
    Next

注意，第一個工作簿和工作表在代碼的更深處但在同一模塊中。

任何幫助表示贊賞。

編輯：

這是模塊的頂部，其中包括設置實際的工作簿和工作表：

'Create new workbook
Dim combinedReports As Workbook, combinedCsats As Worksheet, combinedQualities As Worksheet, combinedTickets As Worksheet
Set combinedReports = Workbooks.Add
Sheets("Sheet1").name = "Combined CSAT's"
Set combinedCsats = combinedReports.Sheets("Combined CSAT's")
Sheets.Add After:=ActiveSheet
Sheets("Sheet2").name = "Combined Qualities"
Set combinedQualities = combinedReports.Sheets("Combined Qualities")
Sheets.Add After:=ActiveSheet
Sheets("Sheet3").name = "Combined Tickets"
Set combinedTickets = combinedReports.Sheets("Combined Tickets")

Answer 1

在For r = 2 to 8循環之前插入此代碼，該代碼將在有故障的對象上停止。

Debug.Print combinedReports.Name
Debug.Print combinedReports.Worksheets("combinedQualities").Name
Debug.Print snowq.Name
Debug.Print snowq.Worksheets("qsum").Name
Debug.Print CAQual.Name
Debug.Print CAQual.Worksheets("CAqsum").Name
