Hi, I am having an issue with making calculations in paraview. For the past year I have previosuly followed the exact same steps to make the calculation of elevation (coordZ - Sealevel) with my files and data, but for some unknown reason I am now getting this error appear.
I am unsure which verison I was using when these steps were working for me (most likely an older one as i downloaded paraview about a year ago). But the issue started occuring out of nowhere in the same version that was previosuly downloaded, so I tried reinstalling and have the same issue.
The error message pops up when I select the minus key on the calculator
