[AccessD] MAny-To-May

Martin:

I actually had it that way - job in the header, equipment in the 
sub-form.  But we had to change the way the jobs are created because of 
the way the job is actually looked at by users.  You pick the equipment 
first now and see the list of jobs for that piece of equipment in the 
sub-form.
