a question compute reduce/region command

I have a colloidal particle system in which I intend to calculate the energy of certain region of the system (near the surface). I have the following portion within the lammps script, where I calculate the pe and ke and then put it in reduce/region command to evaluate it with my region (lowerbox). I defined a variable tel (total energy) which i wanted to printout as the sum of c_pel and c_kel. The simulation is running fine. But the value of v_tel which is getting printed is orders of magnitude larger than the some of c_pel and c_kel
