Addition-Elementary Style

[Michael Mandaville]

Revolution brothers and sisters,
On the basis that the most stupid question is the one left unasked, I throw
myself on the pyre with this question:

I have eight multiple text fields.  Numbers will go into these fields.  I
want all the numbers to add up and go into the Ninth field.


Add field1+field2+field3 [etc.,} and put into field Total

Add field Timeneed + Effort + People [etc.,] and put into field Total


I have searched the documentation and tried a dozen syntaxes but can't seem
to get something as fundamental to work.

Thank you.
