CFD Online Discussion Forums - 'mode' error while running icoReactingMultiphaseInterFoam

Hello dear Friends,
I am trying to model a moving laser using 'icoReactingMultiphaseInterFoam' solver, but I am facing 'mode' error while running the solver.

--> FOAM FATAL IO ERROR: (openfoam-2012)
Entry 'mode' not found in dictionary "/home/sumantya/OpenFOAM/sumantya-v2012/run/laser/constant/radiationProperties"

I can't able to eliminate this error. Please give suggestions on how to tackle this error.
I am attaching my "RediationProperties" file here for reference.
