Hep wanted for keyboard and keypad

Hi !

I have a problem and if I could get some help I would be wery greatfull !

I have a keyboard (10 columns / 4 rows) from Farnell Components with both the usual QWERTY and numerical (4 columns / 4 rows) keypad. The PCB is already designed with pulldown resistors.
On my PIC16F876A I have PORTA for the rows and PORTB & PORTC for the columns and I can't get it to work !!!

So if you could be so wery nice and help me out I would be most greatfull !

Best regards hanseman_61
