**EltonCris**In your screenshot, change those with brown A-Z (string) to 0-9 (numbers) by clicking itself. Clicking it should switch between states.

Here's what I mean:

You can also define calculation values on every rows and column in the matrix field properties.

If you can't get it to work, let us know so we can help you.

**Chriistian**I checked your form and it looks like one of the last fields is still set as a string in the calculation widget. Furthermore, there is a plus sign after the last field. To resolve this, please remove the last plus sign and set the last field as a number.

The calculation should look like the one below:

The order total should be working now after the change.

If you need further assistance, please let us know.

Regards. **SportsInActionPhotos**THANK YOU THANK YOU!

IT WORKS!
