Sum all values in a field



I'm creating a small db in which I have several students, being the name one of the fields, and one field for each month with the amount paid. So far I've been able to create a sum of all months for each student

Sum ( set;out;nov;dez;jan;fev;mar;abr;mai;jun;jul;ago)

but I would like to have a sum for each month of all students, so far I haven't been able to do that.

The purpose is to make a bar chart with the overall income of each month

Any lights would be most appreciated
