Hello MarK_S
Thank you for the simple explanation. I see the goof-up, I forgot to see the pins involved and assumed that the 16F628 would be good as the other, no wonder I went round in circles.
Thanks for setting me in the correct direction, I will try and read the 16F84A details and see what I can achieve..

I was trying to use Ero's code for a 16F628 unwittingly for a circuit that had a 16F84... whoops..

Thanks once again..
