Looping Question When Deleting Rows

For some reason, when I execute this query (to compare values in columns G and J), the loop will stop once it finds two matching values. This is driving me crazy! Any help or guidance would be greatly appreciated.

Sub FindDuplicates()

ActiveSheet.Cells.Select
Dim i As Long
For i = Selection.Rows.Count To 1 Step -1
If ActiveCell.Offset(0, 6).Value <> ActiveCell.Offset(0, 9).Value Then
ActiveCell.EntireRow.Delete
End If
Next i
End Sub
 

Excel Facts

Quick Sum
Select a range of cells. The total appears in bottom right of Excel screen. Right-click total to add Max, Min, Count, Average.
I haven't been able to find it in help (again) but once read that you can't change the number of elements in a collection while you are iterating that collection.

I'm not sure if that applies here but you are changing the terminal variable in your "for / next" statement (selection.rows.count) when you delete a row from that collection while still inside the loop.

You may want to try building a range to be deleted after you exit the loop instead of deleting the row while still in the loop.

Good luck.

Your code is selecting all the cells. A1 is therefore the active cell.

Your loop is starting at the active cell, so it never gets to a row other than row 1.

ActiveSheet.Cells.Select
Dim i As Long<?xml:namespace prefix = o /><o:p></o:p>
  <o:p> </o:p>
  For i = Selection.Rows.Count To 1 Step -1<o:p></o:p>
    If Sheet1.Cells(i, 7).Value <> Sheet1.Cells(i, 10).Value Then<o:p></o:p>
  <o:p> </o:p>
  Sheet1.Rows(i).Delete<o:p></o:p>
  End If<o:p></o:p>
  Next i
End Sub


In case Sheet1 is not the active sheet :-

Code:
Sub FindDuplicates()
ActiveSheet.Cells.Select
Dim i As Long
For i = Selection.Rows.Count To 1 Step -1
    If Cells(i, 7) <> Cells(i, 10) Then Rows(i).Delete
Next i
End Sub

Or, a little more efficient :-

Code:
Sub FindDuplicates()
Dim rws&, i&
rws = Range([A1], ActiveSheet.UsedRange).Rows.Count
For i = rws To 1 Step -1
    If Cells(i, 7) <> Cells(i, 10) Then Rows(i).Delete
Next i
End Sub
