Some days I feel dumber than others and today is one of those!

I tried joining this code with my code and things are not going so well... I have a piezo beeping on the press of the swithes and when I added this code it is more like rigning than beeping and also I have a feeling I need something short and simple but I am trying to use something big and complex.

All I really need is to have a counter that counts the minutes up to 720 and then cycle to 0 and start over endlessly. I don't need an interupt as I can test compare by branching from the main loop (in one minute I have plenty of time to test) Accuracy is not really important + or - 10 minutes over 720 is ok. I am already using timer0 so I guess I need to use timer1 or timer2.

Do you have any simple and quick advice or link to suggest?

I feel I have taked already too much of your time and I apologize for that.
