I need to make the following procedure dynamic. Also there are blank
cells in both column E and column F that need to be skipped over for
the procedure to finish its job. Help greatly appreciated. From a user
standpoint is it easier to activate this from a button?

Sub HideRows()
On Error Resume Next
With Range("E10:F222")
..EntireRow.Hidden = False
For i = 1 To .Rows.Count
If WorksheetFunction.Sum(.Rows(i)) = 0 Then
..Rows(i).EntireRow.Hidden = True
End If
Next i
End With
End Sub
