**RodBush**Can you calculate and display the totals of the columns in a matrix

EG

2 4

4. 6

then display

6. 10

**Charlie**You can fetch the inputs in the matrix field, but you cannot output the total calculation directly on a specific cell. To learn more about matrix field calculations, please check these guides:

We also have the spreadsheet widget where you can perform calculations directly on the cells, here's the link to it: https://widgets.jotform.com/widget/spreadsheet

I hope that helps.
