I have now used 16f876 ( it works ok) instead of 16f84a I did try your sugestions but with no luck so I am going to rebuild with 16f84a again and try another pic.
Thanks for the help.

NEW MESSAGE: I have now got it working! I rebuilt the circuit and it worked OK but one of the LEDs wasnt quite going off but I was working from the book PIC in Practice and the circuit did not show a wire to ground from Vss I fitted that and it is now OK.
