Hello-

I have a code to fill all blanks in column F with an "X". There is
data in Columns A:E down to row 2145, but the code only puts the X
down to row 2135. Cell 2136 is the last filled cell in column F, this
has something to do with it. I want the code to search column F based
on the entire range of column E, in this case E2:E2145.

Sub b()

Dim lngLastRow As Long

Application.ScreenUpdating = False

For lngLastRow = Cells(Cells.Rows.Count, "F").End(xlUp).Row To 2
Step -1
If Cells(lngLastRow, "F") = "" Then
Cells(lngLastRow, "F").Value = "X"
End If
Next lngLastRow

Application.ScreenUpdating = True


End Sub

Please help if possible
