led matrix pic 16f84 and 4017 help me please

[wellyboot]

define osc 4
porta = 0
trisa = 0
portb = 0

this as well:
trisb = 0

porta = %10010
pulsout portb.0,150
pause 10
porta = %11001
pulsout portb.0,150
so on .......

Maybe worth changing the 'pause 10' to 'pause 1' if your display is flickering.

does your 4mhz crystal have 2 caps (18 - 22pf) between each leg and ground?
not shown on your diagram.
