**devincornell**I've recently added a column to a matrix that I perform a calculation on. I added the value into the matrix properties, and added the fields to the calculation but they are not being added.

Matrix: Prizewinner

New Column: Contemporary Set Dance, Value $9

Calculation Field: Regular Dances

Any help would be appreciated.

**candy**Hello,

I have checked your form and cloned it on my side in order to test it.

I have seen that you have set the calculation values to the matrix with no error. However, you have set the Form Calculation widget with false calculation.

You should have added a zero at the beginning of the calculation as you can see the screenshot below:

After setting the right configurations, your form will be able to work properly as you can see the screenshot below:

Please try and if you need any further assistance, let us know.

Thank you for contacting us.
