VBA - VLOOKUP if #N/A is returned Then do something Else Next cell in range
Experts,
I am trying to figure out how to determine if the VLOOKUP formula returns #N/A. I want to find what the formula returns, if it is NOT #N/A, then go to the next cell.
If it IS #N/A, then I want to:
1.Copy cell A (and the row number the #N/A occurs) as well as cell C of the same row.
In my example, that would be A7 and C7.
2. Paste these values into Sheets(Corrected ID-Name), at the first open row at the bottom
In my example, that would be row 7 on corrected ID-Name.
3. Hopefully B8 on Sheet1, will automatically update the Vlookup formula, if not, do I need to say “update calculations, then go on to next cell”?
I understand that the names on Sheet1 column C, are different for the same ID Number, the first one will be copied, whatever that maybe and then from now on, that is what that ID will refer to.
Code and example workbook attached
Thank you,
Kevin

This would be a simple way ot handle it:
If IsError(ActiveCell.Value) Then
...
If IsError(ActiveCell.Value) Then
...

That sort of did it. See attached workbook, sheet corrected ID-Name, your code produced A1:B11, I need it to be like D1:E8, in that it only copies the name once.
After the first copy:
cell.Offset(, -1).Copy Sheet2.Range("A" & Rows.Count).End(xlUp)(2)
cell.Offset(, 1).Copy Sheet2.Range("B" & Rows.Count).End(xlUp)(2)
Is there a way to say "refresh the VLOOKUP", so it would populate SUE ME in cell B8 (sheet1) and thus on the next loop that would be an else, resulting in the name being copied only on the first time an error occurs.

For Each cell In rng.SpecialCells(xlCellTypeFormulas, xlErrors)
On Error Resume Next
If cell.Value = CVErr(xlErrNA) Then
'MsgBox "Found an #N/A"
cell.Offset(, -1).Copy Sheet2.Range("A" & Rows.Count).End(xlUp)(2)
cell.Offset(, 1).Copy Sheet2.Range("B" & Rows.Count).End(xlUp)(2)

rspahitz,
I put that line in, but the messages box never triggers to:
MsgBox "Found an #N/A"
only the else:
MsgBox "Not a #N/A" comes up.

What about this?
Sub VLookUpAutomation()
Dim cell As Range
Dim rng As Range
Sheet1.Activate
ActiveSheet.Columns("B:B").Insert Shift:=xlToRight
ActiveSheet.Range("B1").Value = "VL"
ActiveSheet.Range("B2").FormulaR1C1 = _
"=vlookup(RC[-1],'Corrected ID-Name'!C1:C2,2,FALSE)"
Set rng = [B2]
Set rng = Range(rng, Cells(Cells(Rows.Count, 1).End(xlUp).Row, rng.Column))
If rng.Rows.Count = 1 Then
rng.Select
Else
rng.Cells(1, 1).AutoFill Destination:=rng, Type:=xlFillDefault
End If
For Each cell In rng.SpecialCells(xlCellTypeFormulas, xlErrors)
On Error Resume Next
If cell.Value = CVErr(xlErrNA) Then
'MsgBox "Found an #N/A"
With Sheet2
If IsError(Application.Match(cell.Offset(, -1), .Columns(1), 0)) Then
cell.Offset(, -1).Copy .Range("A" & Rows.Count).End(xlUp)(2)
cell.Offset(, 1).Copy .Range("B" & Rows.Count).End(xlUp)(2)
End If
End With
Else
'MsgBox "Not a #N/A"
End If
On Error GoTo 0
Next cell
End Sub

For mine, replace the word ActiveCell with cell:
For Each cell In rng
If IsError(cell.Value) Then
MsgBox "Found an #N/A"
'copy cell to left and copy cell to right
'paste onto Correct Agent ID-Name
'Using first open row at bottom
'Will vlookup update so that repeated #N/A's are not copyied again?
'If not, do I need to say "recalculate" prior to going on to next cell looking for #N/A
Else
MsgBox "Not a #N/A"
End If
Next cell
For Each cell In rng
If IsError(cell.Value) Then
MsgBox "Found an #N/A"
'copy cell to left and copy cell to right
'paste onto Correct Agent ID-Name
'Using first open row at bottom
'Will vlookup update so that repeated #N/A's are not copyied again?
'If not, do I need to say "recalculate" prior to going on to next cell looking for #N/A
Else
MsgBox "Not a #N/A"
End If
Next cell

rspahitz,
StephenJR beat you to it, but thank you for your comment, I really like your proposed solution, as I have used the ISNA and ISERROR in formulas quite often, so I will try implementing this in future projects.
