Many thanks Albert. I am trying to model a complex system so I will
indeed be building many notebooks and packages.  I scrounged the
package format from somewhere on the internet and then misunderstood
it. So I have a few changes to make! I take your point  on "best
practice". Thanks once again your reply will help get a number of
problems sorted out.
