Error on use calculator

Hi, I’m new using ParaView so I don’t really know how to describe the error I got. But basically I’m trying to use the ParaView calculator and I’m getting the following error:

Does anyone know the reason for the error and how to solve it?

Thank you very much in advance.

OBS: If anyone wants to see the data or how I did the process, attached is the image.

Hi @DanielS_13 ,

Please share your data.

Best,

In the case of value data, right?
I have them attached.
Thanks.

Works great here, using ParaView 5.10.1

Your expression is not correct, it should be:

iHat*"Field 3"+jHat*"Field 4"+kHat*"Field 5"

I had noticed the error later, but still, thanks a lot for the help.
