Thanks, Edgardo, the Physics package does exactly what is needed.

@Preben Alsholm 

 

Great!  Thanks Preben!

@tomleslie 

I can see the attachment at the bottom of the first "Attachment" reply, after the code listing.  Is there something I have to do to make this visible to others?

@tomleslie 

 

Sorry, I'm new here, and the interface to this forum is not very intuitive to me.  Anyway, the program is attached now.

Original Code attached

@tomleslie 

Interesting.  So sum is different from add?

I attached my original code.
