Dear friends, I had made a program to control lab reaction hood function using PIC. In the code there is a timer part and keypad to control a blower,tube light,UV lamp,power socket and door. code is working perfectly until I add error handling statements. If I add one line to the code it reset the program when I simulate the program in Proteus. please help to get rid of this problem.
Here is the code in mikroC:
When this code is simulated in Proteus it restart to beginning if I added the last part of the code..
