the temperature circuit not working on proteus

i have constructed this project on proteus but is not working. i attached the proteus design attached along with the threat. pls can some one help me correct the problem. the code is ajay code from download option of this webpage

ugoo I am sorry to say, but some of the project shared by binu were not working. Thats the reason I stopped posting them on website. Ok i found one issue in the code/circuit.. on circuit you have DS1620 reset connected to P1.7 whereas in code its P1.6. Change that first and then there is little more debugging needed. Can you please make this work, I will update this project and ofcourse credit will go to you.
