PROBLEM ON CODE OF GSM CONTROLLING APPLIANCES THROUGH SMS

Dear members I have a problem, I have prepared the code of GSM CONTROLLING APPLIANCES THROUGH SMS and when I compile it no any error comes after compiling and when i tested it on proteus using PIC16F877A all lights are turned on initially and always remain on until i stopped a simulation. Any one who can collect my code please can help me.. Below it's my code the code was compiled in MikroC for PIC.
