Selecting a row relative to the position of a button

I'm brand new to macros, so I apologize if this is a particularly dumb
question. I'm copying a hidden row and trying to insert it just below
a button on a spreadsheet. The location of the button will be
variable, so I need the row to be inserted relative to the position of
the button. Here's what I have so far:

Sub Button64_Click()
'
'
ActiveSheet.Unprotect Password:="test"
Rows("9").EntireRow.Hidden = False
Rows("9:9").Select
Selection.Copy
Rows("22:22").Select
Selection.Insert Shift:=xlDown
Rows("9").EntireRow.Hidden = True
ActiveSheet.Protect Password:="test"
End Sub

Instead of 'Rows("22:22").Select', I need to select the row immediately
after the button.

I'm sure there's a much more elegant way to do this, so any suggestions
are very welcome!

Thanks so much!
