when I interpreting the code I receiving :
two "parse error" for the highlighted lines . what is wrong in the code?

#include "udf.h"
DEFINE_SOURCE(energy_udf,c,t,dS,eqn) 
{ 
real source; 
if(N_TIME > 0) 
{ 
if (C_T(c,t) > C_T_M1(c,t)) 
{  
if (C_T_(c,t)<=297. && C_T(c,t)>=287.) 
{ 
source =(-0.0235*pow(temp,3.))+(20.246*pow(temp,2.))-(5816.7*pow(temp,1.))+557045;  
dS[eqn] =(-0.0705*pow(temp,2.))+(40.492*pow(temp,1.))-5816.7 ; 
} 
}
else if (C_T(c,t) < C_T_M1(c,t)) 
{ 
if (C_T_M1(c,t) <= 285.0 && C_T(c,t) >= 297.0) 
{ 
source =(-0.0227*pow(temp,3.))+(19.483*pow(temp,2.))-(5568.7*pow(temp,1.))+530603;
dS[eqn] =(-0.0681*pow(temp,2.))-(38.966*pow(temp,1.))-5568.7; 
} 
} 
} 
return source; 
}

when I compiling the code I reciving the below errors
..\..\src\test.c(36) : warning C4003: not enough actual parameters for macro 'C_T_'
..\..\src\test.c(36) : error C2059: syntax error : ')'
..\..\src\test.c(51) : error C2059: syntax error : 'return'
..\..\src\test.c(52) : error C2059: syntax error : '}'

any helps ?
