I would guess each rectangle has an on_click event so just pass some
indentifier as an arguement to your macro. Something like this
Private Sub Rectangle1_Click()
yourmacro "rec1"
End Sub
Private Sub Rectangle2_Click()
yourmacro "rec2"
End Sub

then for your macro

Sub yourmacro(WhichRectangle as String)
your code here
End Sub

the value WhichRectangle will tell you what was clicked to start your macro

I have a macro assigned to a number of rectangles. When a
specific rectangle is clicked to activate the macro, I
need the macro to identify which rectangle (ex: "Rectangle
3") was clicked to activate the macro.
How would I do that?
