I've been assigned a task at work but am rather unfamiliar with VBA code (or coding in general). My goal is to automatically hide/unhide rows based on the value of 2 different cells. I've found the following code that is working but I am struggling to adjust it so it will check the value of cell B13 in addition to B12. I want to ensure someone cannot enter information into cell B13 then accidentally hide it by removing the information from cell B12. 

```
Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Address = "$B$12" Then
If Target.Value = "" Then Rows("13").EntireRow.Hidden = True
If Target.Value <> "" Then Rows("13").EntireRow.Hidden = False
End If
End Sub

```

Any guidance would be very much appreciated!
Cheers!
