So I have tried this with Thomas Elmigers rpn plugin, found here:

<$macrocall $name="rpn" a={{!!field1}} b={{!!field2}} operation="+" 2/>

<$macrocall $name="rpn" a={{!!field3}} b={{!!field4}} operation="+" 2/>

It is also not possible to add more than 2 fields in a macrocall.

But how can I add the results of each of these expressions? (Has it 
something to do with the listwidget you mentioned?)

Perhaps anyone has an idea for a completely other solution of the problem 
(see first post). [Please not: An external link to an Excel spreadsheet ;-)]
