Weird, the text version of the notebook had code that was not
displayed at all (below id=25).
I deleted it from the text version, restarted the notebook, evaluated
all, it worked, I did this a couple of times and then again: boom. The
interesting thing is that if I repeated the last command manually, it
evaluated, so it was not that the definition of dwaterv was not
evaluated at all, but the cell dwaterv.subs(locals()) must have been
evaluated before the definition. See code below (id=31 was put in
after Evaluate All).
