P18F4550 sensors interfacing help

hi everyone,
i had to interface two sensors to p18f4550 microcontroller,temperature sensor to AN0 channel and humidity sensor to AN1 channel. i wrote program in MPLAB IDE using interrupts. i am getting humidity value on hyperterminal but temperature value is missing.could any one who is familier please help me..

What are the part numbers and the manufactures of the sensors you have used in your design?

LM35 temperature sensor and HIH-4000-101 humidity sensor. could you please tell me the mistake in the program where i used interrupts..
