Add contents of a column

Can anyone help? Is there a way to add the contents of one column together? I have a column that is calculating how many points each pupil in a class has but I want to know the class total.- not a class average, which I know how to do. Is there a function that will allow me to add the individual totals?
Thanks

I think I replied a few minutes ago exactly the same question by e-mail...
