PIC18F25k22 configuration - I/O problem

Hello all,

I started to use the PIC18F25k22 SSOP package. From the very beginning, I have a problem with using this microcontroller. I wrote a test program to try out all the peripherals that are on the PCB. The problem with reading switches that are connected to PORTA.6 I PORTA.7 and also is a problem at PORTC.7. I do not know what to do. This PIC18F25K22 is driving me crazy. The complete test program I attach to the message. Any help is welcome.

Thank a lot in advance!
