John,

I am sorry that I am not better at explaining what I need.  What you gave me
works fine to retrieve the last row in the database however I need to get
the last balance of a single customer  custid=1  or  custid=7.  I am trying
to use this in a form and I added to what you gave me where custid=custid
but it did not work.  can you help??

Thanks,

David
