Next Without For error in nested loop in Excel VBA
提问by Rich W
I am trying to figure out a way to run a Vlookup on a Cell in my "System File" by checking a table in a "New Data" File. HOWEVER, if there is an #N/A error, I want the cells' values to be unchanged. I've come up with the following, however, I keep getting a "Next without For" error. Is it possible to escape a nested For Next loop?
我试图通过检查“新数据”文件中的表来找出一种在“系统文件”中的单元格上运行 Vlookup 的方法。但是，如果出现 #N/A 错误，我希望单元格的值保持不变。我想出了以下内容，但是，我不断收到“Next without For”错误。是否可以转义嵌套的 For Next 循环？
The tl;dr semantic version:
tl;dr 语义版本：
For i 1 to 10
For j 1 to 3
Something with .Cells(i,j)
Set range X = .Find(thing
If X = Nothing Then
Next j *** <THIS IS WHERE MY ERROR IS THROWN
Else
-Do Something with X-
End if
Next j
Next i
My more or less actual code is as follows:
我或多或少的实际代码如下：
Sub Thing()
Dim SysWS As Worksheet
Dim NewDataWS As Worksheet
Dim NDSKUs As Range ' This is set to the first column of the NewDataWS
Dim NDMonthsRow As Range ' This is set to the first row of the NewDataWS
Dim SKU2look4 As String, Month2look4 As String
Dim ifoundtheSKU As Range 'the result of finding SKU2look4 inside of NDSKUs range
Dim ifoundtheDate As Range 'the result of finding Month2look4 inside of NDMonthsRow range
Dim i As Integer, j As Integer
Dim workzone As Range 'The Cell being evaluated
For i = 2 To SysWS.UsedRange.Columns.Count
For j = 2 To SysWS.UsedRange.Rows.Count
Set workzone = SysWS.Cells(j, i)
SKU2look4 = SysWS.Cells(j, 1) 'SKUs are along the left column
Month2look4 = SysWS.Cells(1, i) 'Dates are along the top row
'1-Find the right Date Column for extraction
Set ifoundtheDate = NDMonthsRow.Find(What:=Month2look4, LookIn:=xlValues, _
LookAt:=xlWhole, SearchOrder:=xlByRows, SearchDirection:=xlNext, _
MatchCase:=False, SearchFormat:=False)
If ifoundtheDate Is Nothing Then
Debug.Print (Month2look4 & " -Date NOT Found in New Date File")
******Next j******
Else
Debug.Print ("ifoundtheDate:" & ifoundtheDate.Address)
End If
'2-Find the row
Set ifoundtheSKU = NDSKUs.Find(What:=SKU2look4, LookIn:=xlValues, _
LookAt:=xlWhole, SearchOrder:=xlByRows, SearchDirection:=xlNext, _
MatchCase:=False, SearchFormat:=False)
If ifoundtheSKU Is Nothing Then
Debug.Print (SKU2look4 & " Not Found in the New Data File")
*********Next j******
Else
Debug.Print ("ifoundtheSKU:" & ifoundtheSKU.Address)
End If
'Set the "workzone" cell's value to that of the found row offset by the found column
workzone = ifoundtheSKU.Offset(, (ifoundtheDate.Column - 1))
Next j
Next i
Of course the ***s are not actually in there. Any thoughts on how I can accomplish this? Thanks in advance
当然，***实际上并不在那里。关于我如何做到这一点的任何想法？提前致谢

For i = 1 to 10
For j = 1 to 3
Something with .Cells(i,j)
Set rngX = .Find(thing)
If Not rngX Is Nothing Then
Set rngY = .Find(thingelse)
If Not rngY Is Nothing Then
'something with rngX and rngY
End If
End if
Next j
Next i

Use
用
For i=1 to 10
For j=1 to 3
Something with .Cells(i,j)
Set range X = .Find(thing
If X = Nothing Then
Goto Nextj *** <THIS IS WHERE MY ERROR IS THROWN
Else
-Do Something with X-
End if
NextJ:
Next j
Next i

Exit For terminates the current for loop early (the inner one in your case).
Exit For 提前终止当前的 for 循环（在您的情况下是内部循环）。
