After I have used it, an additional question has surfaced.
Can I make the reference dynamic, as it is now I have to mark it and pres F9 to update, cant it do that automatical?
Can I link 2 different mathcad files so that I in file 1 define a variable A, and then in file 2 can write A= and the value as defined in file 1 appears.
Hope it makes sense.
