Problem with sum function

Hello
I have some integers and i want to sum them, but I'm getting "Error: [row :
20] Missing calculation." I'm using sum function from XLSform. I
understand, that I'm missing something, but what?

I'm sorry, I give wrong name: instead "calculation" field I named it
"calculate".
