How to add a row total

I just tried to add the data in the field.

Is there any options there.

Customized format is not getting

You have to share a bit more detail on what you are trying to do - maybe a screenshot would be helpful?

Only thing I can think of now is you should be able to add number values across a row using a custom expression. Make sure the fields have number type (a # in front of them in for example filter menu).

But again, it’s much easier to help if others can see what you see on the screen!
