I'm trying to select X rows for a sort. The first and last rows have
a defined name, RSTART and RLAST. They look
like this in the Define Name dialog: ='MySheet'!$15:$15 ....

How do you select the rows using these names. Here's the macro output
of my best shot. I can't figure out how to incorporate the second
name. Thank you.

Sub trythis()

Application.Goto Reference:="RSTART"
Rows("15:59").Select '<---- Held down shift key and selected
RLAST in cell address combo
Range("I15").Activate ' what is this?
Selection.Sort Key1:=Range("B15"), Order1:=xlDescending,
Header:=xlGuess _
, OrderCustom:=1, MatchCase:=False,
Orientation:=xlTopToBottom, _
DataOption1:=xlSortNormal

End Sub
