**Chriistian**It looks like the values from the Matrix are being displayed as text instead of calculation values, which is why they are not being calculated by the Form Calculation Widget.

To resolve this issue, open your calculation widget and click on the a-z section of each fields.

Once all the fields are orange and 0-9, the calculation widget should now calculate the matrix correctly.

If you need further assistance, please let us know.
