Hi Travis,

This is very helpful thank you.  However, is there a way to make it not be
less than a 1.  As it's written below someone with one job gets a zero and
someone with no jobs gets a NULL.  It would be great if someone with  1 job
got a 1 and someone with zero jobs got a 0.

Thanks again,

Richard
