Excel - automatically hiding select rows based on drop down selection

Hi there! I have a drop down selection of 10 items on my dashboard tab and am trying to only show rows 57 to 72 when I select one of them. I am using the following code but somehow it is not working and my dashboard does not change at all. However, when I key in something into a random cell, the page reloads and rows 57:72 become hidden. But then, it stays the same across all my selections and I cannot unhide it again through the drop box selection. May I know if anyone has an alternative suggestion? Thank you in advance!

 

Private Sub Worksheet_Change(ByVal Target As Range)

If Target.Column = 2 And Target.Row = 3 And Target.Value = "1"

Then Application.Rows("57:72").Select Application.Selection.EntireRow.Hidden = False

Else Application.Rows("57:72").Select Application.Selection.EntireRow.Hidden = True

End If

End Sub
