Don't know exactly what you are wanting to do. The Change macro is written:
Private Sub Worksheet_Change(ByVal Target As Range)

End Sub
Leave those two line alone.
If you want the macro to call the getRvalues macro when K2 changes, do this:
Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Address(0,0) = "K2" Then Call getRvalues
End Sub

If you want to set myRange for some reason use:
Private Sub Worksheet_Change(ByVal Target As Range)
Dim myRange As Range
Set myRange = Worksheets(1).Range("K2")
If Target.Address(0,0) = "K2" Then Call getRvalues
End Sub
But I don't know what you want to do with myRange.
If Worksheets(1) is the sheet that holds this code, just say Set myRange =
Range("K2")

I am trying to write a macro that pulls R values from trendlines any time a
common variable is changed. The variable is stored in "k2," and I have
tried
to run this using the following code placed in "ThisWorkbook":

Public myRange As Range
Set myRange = Worksheets(1).Range("K2")
Private Sub Worksheet_SelectionChange(ByVal myRange As Excel.Range)
Call getRvalues
End Sub

It's not working, and I'm not sure why. I bet it has something to do with
my range declaration, but can someone confirm that? When I'm working with
events, what's the proper way to declare variables and objects relating to
these events?

Thanks,
