Chemkin mechanism issue

[SoheibX]

I tried to use the below chemkin mechanism in my combustion simulation project, but when i add it i get an error message that says:" error: Invalid THERMO data (thigh<tmid) at line no. 3.n
Error Object: #f ".

It appears the problem is in the thermodynamics file, i tried to solve it but without any result.
