How to use more than two temperature ranges of Chemkin thermodynamic data in Fluent

  Hello,
  
  I am trying to simulate air dissociation effect in hypersonic flow. I import Chemkin mechanism into Fluent. For the thermodynamic data, when I just use two temperature ranges, it works fine, the two temperature range format is as followings:
  
  However when I tried to use three temperature ranges:
  
  Fluent gives me Error: Invalid THERMO data at line no. 18.n.
  
  I checked the "Chemkin-Pro Input Manual", it says "using more than two temperature ranges", the format should be like this. Is it that Fluent does not support more than two temperature ranges?
  
  Could someone help me here?
  
  Thank you,

  Hello! Are there anyone who can help me with my question?
  
  It seems that after changing from "ANSYS customer portal support" to this "student community", it becomes quite difficult to get support from ANSYS support engineers.

  I use my own defined mechanism. It looks like this:
  
  REACTIONS
  
  O2+M<=>2O+M 3.610E+18 -1.000 117968.40
  
  REV/ 3.01E+15 -0.500 0.00/
  
  O2/ 9.00/ N2/2.00/ O/ 25.00/ N/ 1.00/ NO/ 1.00/
  
  .....
  
  end
  
  Thanks,
