Need Help with MPLAB and Proteus

Hello everyone,

I need help with a project. I am doing a microcontroller project (Digital RPM meter). I am trying to run my .c file in MPLAB but there is error message. I am new to MPLAB and Proteus and I have spent plenty of time trying to solve the problem. I need to compile the .c file in MPLAB, have the .hex file and run it in Proteus.

I got the project from here:

http://www.pyroelectro.com/tutorials/digital_tachometer_rpm/

This is the .c file:

This is the schematic of the circuit:

This is the Proteus file (incomplete):

can anyone help me to complete the project?
