Digital thermometer with icl7107 and lm35(showen in three 7-segment displays)

I have to make the circuit as the hardware application project,
it must show 2 digits and 1 digit after comma(exmple: 22,3).
the proteus similation i made works well but the circuit on the breadboard doesn't work,
and actually at one time i succied to see output when the analog input increases digital output decreases,when the analog input decreases digital output increases.
please heellllp!

Hi!
You could put more design details and proteus file, if possible?
Thank you!
