[Paraview-developers] Error using Paraview calculator

[egoli2]

Hi everyone 

When I use calculator in Paraview to change the value of the one of the
output I get this error: 

---------------------------------------------------------------------------------------------------------------- 
ERROR: In

vtkPVArrayCalculator (0x6e6f900): An error occurred when parsing the
calculator's function.  See previous errors. 

----------------------------------------------------------------------------------------------------------------------------------------- 

it happens when I type a + or - or * next to the temperature (the main field
in my simulation). 

And, by the way, the apply button is always off! I do not know really why! 

Do you have any idea to avoid this problem? 

Best, 
Elyas
