I am using funkysetfields to introduce my initial conditions of temperature and pressure in fluid region of a chtmultiregionfoam case,

expressions
 ( 
   T.air
    {
     field T;
     variables "T0=300;Z=pos().z;gamma_1=10;gamma_2=0.005;";
     expression "Z <= 200 ? T0+(gamma_1)*(Z) : ( Z<=350 ? T0+(gamma_1)*200 : (T0+(gamma_1)*200)-(0.005)*(Z-350))";
      keepPatches 1;
     }

  p.air
    {
    field p;
     variables "T0=300;P0=100000;gamma_1=0.01;gamma_2=0.005;Z=pos().z;R=8.13;";
     valueExpression "Z <= 200 ? P0*(pow((1-(gamma_1)*Z/T0),7.9)) : (Z<=350 ? P0*(pow((1-(gamma_1)*200/T0),7.9)) : (P0*(pow((1-(gamma_1)*200/T0),7.9)))*((pow((1-(gamma_1)*(Z-350)/T0),16))))";
 keepPatches 1;
     }
);

i get this error :
Create time

Time = 0

would you please guide me?
