ds1302 8051

Hi
I need ur kind help. I want a sample program for DS1302 interfacing with 8051. This is for my polytechnic project. I already have one sample program. But I guess there is something wrong with the program because the LCD displays ??:??:??(Question mark and semi-colon) It is supposed to display time. Pls send me a sample program or check the program I`ve attached to this message.The other components I`m using in this project is DAC, Speed control board, DC motor and MAX202 for LCD.
Thanks.
