I am just now seeing your post or I would have stopped by. Glad you were smart to come to this DB board b/c I can tell you that is saved my sanity and my M.
Before going into a long post.....as I usually do.... .....I would like to ask you to clear something up for me, please. Why do you say that the LRT would not work on your W? What do you see the LRT as being?
I'll be anxious to hear from you.
Take care, Sandi
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
