?Your zip file has no code in it?...
If you mean to select all down to J65536 this will do it,
Sub DoIt1()
ActiveSheet.Range("A6:J65536").Select
End Sub
If you mean to just select all down to (some range that has yet to be found) maybe this will do it,
Sub DoIt2()
Dim Val1 As Range, MyChoice As String
'(write your own code to find MyChoice...Example is an Input box)
MyChoice = InputBox("Insert your range here")
'(end of your code)
Set Val1 = Range(MyChoice)
ActiveSheet.Range("A6", Val1).Select
End Sub
