hi guys , may i have your help on this code ?
i run my udf and i face these errors :

line 50: function "CX_Message" not found (pc=24).
line 50: function "CX_Message" not found (pc=124).
line 50: function "CX_Message" not found (pc=190).
line 50: function "CX_Message" not found (pc=335).
line 50: function "CX_Message" not found (pc=394).
line 50: function "CX_Message" not found (pc=451).
line 50: function "CX_Message" not found (pc=488).

there's no line 50 !
here is my code :

#include "udf.h"

double h = C_T(c,t);

k = ( 1 + 64.7*aa*bb*cc*dd*ee)*0.613;
Message ("k = %g\n",k);


return (float)k;
}
i'll waiting for your answers guys
thank you all
